2024-01-09 11:57:12 | L'augmentation préoccupante des attaques centrées sur l'identité: tendances et faits The Concerning Rise in Identity-Centric Attacks: Trends and Facts (lien direct) |
Identity threats are by no means a new type of crime. But in today\'s increasingly digitized world, there are more opportunities for bad actors to steal identities and engage in identity-centric attacks than ever before. Unfortunately, user identities are tough for businesses to protect. The fact that these types of attacks are skyrocketing is evidence of that-in the past year alone the Identity Defined Security Alliance reports that a whopping 84% of companies experienced an identity-related security breach. In this post, we\'ll take a look at identity attack statistics and trends and provide some recent case studies to illustrate how some attacks work. We\'ll also highlight one of the most important identity threat facts-that the human element plays a crucial role in the success of these attacks. Understanding identity-centric attacks There are many types of identity attacks. When most people think of these types of crimes, they often imagine traditional identity theft scenarios: Financial identity theft, where a criminal gains access to a victim\'s financial data, like their credit card details, bank account numbers or Social Security number, to make unauthorized purchases, withdraw funds or open new accounts. Tax identity theft, where a bad actor uses a victim\'s personal information to file false tax returns and claim refunds, diverting the money to their own accounts. Employment identity theft, where a fraudster uses a victim\'s identity to get a job, potentially causing issues for that person when discrepancies arise in their employment and tax records. But identity-based attacks also target enterprises and their online users. The cybercriminals behind these attacks might aim to steal sensitive data, siphon off funds, damage or disrupt systems, deploy ransomware or worse. Those are the types of identity attacks we\'re covering here. Identity threat trends and tactics In short, identity-centric attacks are a practical calculation by bad actors: Why would they invest their time and resources to build exploits to help them get in through a virtual back door when they can just walk through the front door? But before they reap the rewards, they still have some legwork to do. Here are a few techniques that cybercriminals use to progress identity-based attacks against businesses and their users: MFA bypass attacks. Many businesses today use multifactor authentication (MFA) to protect the account of their users. It\'s more secure than using passwords alone. But of course, bad actors have found new ways to bypass commonly used MFA methods. MFA fatigue attacks are one example. People-activated malware. People often give life to malware when they fall for a phishing scam or other social engineering tactics. Malware can appear in the form of a .zip file, QR code, .html link, MS Office file and more-there are at least 60 known techniques to plant people-activated malware on corporate networks. Active Directory (AD) attacks. Most enterprises today use AD as a primary method for directory services like user authentication and authorization. Cybercriminals are keen to target AD, which touches almost every place, person and device on a network. This approach works very well, too-more than half of identity-related breaches can be traced back to AD. Cached credentials harvesting. Cached credentials are commonly stored on endpoints, in memory, in the registry, in a browser or on disk. Attackers use various tools and techniques to collect these credentials and gain access to more privileged identities. Once they have harvested these credentials, they can use them to move laterally and log into different applications. Adversaries are likely to find a good “crop” when they are harvesting cached credentials. Recent research from Proofpoint found that more than one in 10 endpoints have exposed privileged account passwords, making it one of the most common identity risks. Keep in mind that cybercriminals are always innovating, and they are quick to build or adopt tools that | Ransomware Malware Tool Threat Studies | Uber | ★★ |

2023-11-27 09:26:51 | 8 sujets essentiels de cybersécurité à inclure dans votre programme de formation 8 Essential Cybersecurity Topics to Include in Your Training Program (lien direct) |
Your employees have a critical role to play as a first line of defense against cyberthreats. But to be effective, they need to know what those threats are-and stay apprised of how they\'re evolving. A comprehensive security awareness program is the key to helping your users grow their understanding of attackers\' methods and objectives so they can become more proactive defenders. That includes knowing what strategies malicious actors employ to manipulate people so they can use them to enable their campaigns. The importance of security awareness It\'s well worth taking the time to craft a meaningful and engaging security awareness program. By presenting the right mix of information to your users in a compelling way, you can empower them to help you improve your organization\'s security posture as well as create a more robust security culture overall. The cybersecurity topics that you include in your program should be relevant to your business and industry, of course. Companies face different cyberthreat challenges and regulatory compliance requirements related to data protection and data privacy. That said, there are several subjects that almost any modern business, regardless of its industry, will want to ensure its employees understand. We list eight of these cybersecurity topics below. They are the go-to approaches and tools that attackers around the world commonly use to compromise users and their accounts, disrupt normal business operations, steal money or data, and do other damage. Here\'s a high-level overview of these eight must-know cybersecurity topics: 1. Social engineering Social engineering is a collection of techniques malicious actors use to manipulate human psychology. Attackers rely on these strategies to trick or threaten users to take actions such as giving up account credentials, handing over sensitive data, running malicious code and transferring funds. They do this by taking advantage of users\': Emotions, by conveying a sense of urgency, generating excitement about an opportunity, or creating fear around losing money or doing something wrong Trust, by posing as someone familiar to the user or a trusted brand or authority-such as the Internal Revenue Service (IRS), UPS, Amazon or Microsoft Fatigue, by timing attacks when users are likely to be tired or distracted and more inclined to let their “emotional mind” guide their decision-making Common social engineering tactics include phishing-which we cover in the next section-and these others: Social media reconnaissance. Attackers often turn to social media to gather information about users that they target with their campaigns. These efforts can include direct outreach to users. Vishing (voice phishing) and smishing (SMS/text phishing). Vishing is the fraudulent practice of making phone calls or leaving voice messages purporting to be from a trusted brand or authority. With smishing, attackers use text messages to send SMS messages to users or robocall them. The messages often promise gifts or services in exchange for payment. Telephone-oriented attack delivery (TOAD). TOAD attacks start with an email that claims to be from a legitimate source and includes a phone number for customer assistance. Callers are connected to fake customer service representatives who then direct the victim through the attack. They may instruct the victim to let them access their machine remotely or download a file that turns out to be malware. Or they might direct them to a phishing site. Common sense can go a long way toward preventing a social engineering attack. Make sure to reiterate that if a message seems too good to be true, it\'s very likely a scam. And if something doesn\'t look or sound right, it probably isn\'t. 2. Phishing Phishing is an example of social engineering. Most phishing messages are sent by email. But some attackers deliver these messages through other methods, including smishing and vishing. Here are some typical strategies: Malicious links.

2023-11-21 08:35:02 | Prévenir les attaques de fatigue du MFA: sauvegarder votre organisation Preventing MFA Fatigue Attacks: Safeguarding Your Organization (lien direct) |
Gaining access to critical systems and stealing sensitive data are top objectives for most cybercriminals. Social engineering and phishing are powerful tools to help them achieve both. That\'s why multifactor authentication (MFA) has become such an important security measure for businesses and users. Without MFA as part of the user authentication process, it is much less challenging for an attacker with stolen credentials to authenticate a user\'s account. The primary goal of MFA is to reduce the risk of unauthorized access, especially in situations where passwords alone may not provide enough protection. Even if an attacker steals a user\'s password, with MFA they still need the second factor (and maybe others) to gain access to an account. Examples of MFA factors include biometrics, like fingerprints, and signals from user devices, like GPS location. MFA isn\'t a perfect solution, though-it can be bypassed. Adversaries are relentless in their efforts to undermine any security defenses standing in the way of their success. (The evolution of phish kits for stealing MFA tokens is evidence of that.) But sometimes, attackers will choose to take an in-your-face approach that is not very creative or technical. MFA fatigue attacks fall into that category. What are MFA fatigue attacks-and how do they work? MFA fatigue attacks, also known as MFA bombing or MFA spamming, are a form of social engineering. They are designed to wear down a user\'s patience so that they will accept an MFA request out of frustration or annoyance-and thus enable an attacker to access their account or device. Many people encounter MFA requests daily, or even multiple times per day, as they sign-in to various apps, sites, systems and platforms. Receiving MFA requests via email, phone or other devices as part of that process is a routine occurrence. So, it is logical for a user to assume that if they receive a push notification from an account that they know requires MFA, it is a legitimate request. And if they are very busy at the time that they receive several push notifications in quick succession to authenticate an account, they may be even more inclined to accept a request without scrutinizing it. Here\'s an overview of how an MFA attack works: A malicious actor obtains the username and password of their target. They can achieve this in various ways, from password-cracking tactics like brute-force attacks to targeted phishing attacks to purchasing stolen credentials on the dark web. The attacker then starts to send MFA notifications to the user continuously, usually via automation, until that individual feels overwhelmed and approves the login attempt just to make the requests stop. (Usually, the push notifications from MFA solutions require the user to simply click a “yes” button to authenticate from the registered device or email account.) Once the attacker has unauthorized access to the account, they can steal sensitive data, install malware and do other mischief, including impersonating the user they have compromised-taking their actions as far as they can or want to go. 3 examples of successful MFA fatigue attacks To help your users understand the risk of these attacks, you may want to include some real-world examples in your security awareness program on this topic. Here are three notable incidents, which are all associated with the same threat actor: Uber. In September 2022, Uber reported that an attacker affiliated with the threat actor group Lapsus$ had compromised a contractor\'s account. The attacker may have purchased corporate account credentials on the dark web, Uber said in a security update. The contractor received several MFA notifications as the attacker tried to access the account-and eventually accepted one. After the attacker logged in to the account, they proceeded to access other accounts, achieving privilege escalation. One action the attacker took was to reconfigure Uber\'s OpenDNS to display a graphic image on some of the company\'s internal sites. Cisco.

[Eye on Fraud] A Closer Look at the Massive 72% Spike in Financial Phishing Attacks
With attackers knowing financial fraud-based phishing attacks are best suited for the one industry where the money is, this massive spike in attacks should both surprise you and not surprise you at all.
When you want tires, where do you go? Right – to the tire store. Shoes? Yup – shoe store. The most money you can scam from a single attack? That\'s right – the financial services industry, at least according to cybersecurity vendor Armorblox\'s 2023 Email Security Threat Report.
According to the report, the financial services industry as a target has increased by 72% over 2022 and was the single largest target of financial fraud attacks, representing 49% of all such attacks. When breaking down the specific types of financial fraud, it doesn\'t get any better for the financial industry:
51% of invoice fraud attacks targeted the financial services industry
42% were payroll fraud attacks
63% were payment fraud
To make matters worse, nearly one-quarter (22%) of financial fraud attacks successfully bypassed native email security controls, according to Armorblox. That means one in five email-based attacks made it all the way to the Inbox.
The next layer in your defense should be a user that\'s properly educated using security awareness training to easily identify financial fraud and other phishing-based threats, stopping them before they do actual damage.

First-Ever Attack Leveraging Kubernetes RBAC to Backdoor Clusters
(published: April 21, 2023)
A new Monero cryptocurrency-mining campaign is the first recorded case of gaining persistence via Kubernetes (K8s) Role-Based Access Control (RBAC), according to Aquasec researchers. The recorded honeypot attack started with exploiting a misconfigured API server. The attackers preceded by gathering information about the cluster, checking if their cluster was already deployed, and deleting some existing deployments. They used RBAC to gain persistence by creating a new ClusterRole and a new ClusterRole binding. The attackers then created a DaemonSet to use a single API request to target all nodes for deployment. The deployed malicious image from the public registry Docker Hub was named to impersonate a legitimate account and a popular legitimate image. It has been pulled 14,399 times and 60 exposed K8s clusters have been found with signs of exploitation by this campaign.
Analyst Comment: Your company should have protocols in place to ensure that all cluster management and cloud storage systems are properly configured and patched. K8s buckets are too often misconfigured and threat actors realize there is potential for malicious activity. A defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) approach is a good mitigation step to help prevent actors from highly-active threat groups.

2022-10-13 10:00:00 | The biggest concerns within the US Financial Sector in 2022 (lien direct) | This blog was written by an independent guest blogger. The value of digital payment transactions is growing as the world's payment environment moves more and more away from cash. Over the past few years, BFSI (Banking, Financial Service, and Insurance) firms have continued to be a top target for hackers. In fact, the Sixth Annual Bank Survey found that more than 70% of fintech companies named information security as their top issue. According to VMware's Modern Bank Heists study, since the COVID-19 epidemic, there have been 238% more cyberattacks on companies in the financial sector. Artificial intelligence (AI) and self-learning malware are making cyberattacks more sophisticated. While ransomware assaults are the most profitable for cybercriminals, phishing attacks prey on unsuspecting and defenseless consumers. Thus, it should come as no surprise that 39% of financial industry executives think that the overall network security threat to BFSI sector companies has increased significantly. Financial and banking firms in the US must put cybersecurity first above all else given the volume of sensitive data that the BFSI sector must manage. Leading analytics company GlobalData predicts that rising demand for cybersecurity would cause worldwide security revenues in the retail banking industry to climb from $7.9 billion in 2019 to $9.8 billion in 2024. What are the biggest concerns facing the financial sector in the United States for 2022? Reimbursing cyber scams As banks are under pressure to compensate their scammed consumers, rising cybercrime rates translate to rising costs for the industry. More than half (58%) of those who conduct their banking online encounter scams via email or SMS at least once per week, and 23% report having fallen victim to a cyberattack. Banks currently reimburse authorized push payment (APP) fraud at an average rate of 46%. Although many banking institutions are refusing reimbursements for online fraud, this is due to change soon, or else the situation will backfire. For example, measures supported by the UK government will require banks to reimburse everyone. This is only one illustration of the fact that if banks are to secure their consumers and their business line in 2022, they must prioritize cybersecurity more highly. To exchange efficient strategies, banks will need to collaborate with governments and industry organizations. The public must continue to get education on preventative measures, but ultimately it is the banks' responsibility to establish security models that will give them and their clients the greatest level of safety. Maintain compliance with strict privacy regulations The use of social engineering and account takeover fraud will increase over the next years. Financial institutions must not only conduct comprehensive data checks beyond document verification at account opening to fight this but also keep track of customer identities throughout the customer lifecycle.

Hacker Pwns Uber Via Compromised VPN Account
(published: September 16, 2022)
On September 15, 2022, ride-sharing giant Uber started an incident response after discovering a data breach. According to Group-IB researchers, download file name artifacts point to the attacker getting access to fresh keylogger logs affecting two Uber employees from Indonesia and Brazil that have been infected with Racoon and Vidar stealers. The attacker allegedly used a compromised VPN account credentials and performed multifactor authentication fatigue attack by requesting the MFA push notification many times and then making a social-engineering call to the affected employee. Once inside, the attacker allegedly found valid credentials for privilege escalation: a PowerShell script containing hardcoded credentials for a Thycotic privileged access management admin account. On September 18, 2022, Rockstar Games’ Grand Theft Auto 6 suffered a confirmed data leak, likely caused by the same attacker.
Analyst Comment: Network defenders can consider setting up alerts for signs of an MFA fatigue attack such as a large number of MFA requests in a relatively short period of time. Review your source code for embedded credentials, especially those with administrative privileges.

2022-08-18 08:00:00 | Ukraine and the fragility of agriculture security (lien direct) |  By Joe Marshall.The war in Ukraine has had far-reaching global implications and one of the most immediate effects felt will be on the global supply chain for food. This war-induced fragility has exposed the weaknesses of how we feed ourselves globally. Ransomware cartels and other adversaries are well aware of this and are actively exploiting that fragility. For the past six years, Cisco Talos has been actively involved in assisting public and private institutions in Ukraine to defend themselves against state-sponsored actors. Our involvement stretches the gamut from commercial to critical infrastructure, to election security. Our presence has afforded us unique opportunities and observations about cybersecurity in a macro and micro way. Ukraine has been a frequent victim of state-sponsored cyber attacks aimed at critical infrastructures like power and transportation. Talos is proud to stand with our partners in Ukraine and help defend their critical networks and help users there maintain access to necessary services. Now that Russia has invaded Ukraine, those threats have escalated to kinetic attacks that are wreaking havoc on a critical element of our world: agriculture and our global food supply chain. Even worse is the implications this war will have for future cyber attacks, as fragility is considered a lucrative element in deciding victimology by threat actors like ransomware cartels. To truly grasp the implications of the war in Ukraine, we have to examine how vital Ukrainian agriculture feeds the world, the current state of affairs, and what this means for the global cybersecurity posture to protect agricultural assets. Where there is weakness, there is opportunityRansomware cartels and their affiliates are actively targeting the agricultural industry. Moreover, these actors have done their homework and are targeting agricultural companies during the two times of the year where they cannot suffer disruptions: planting and harvesting. Per the published FBI PIN Alert: “Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production.” This is far from unusual for these adversaries - they are shrewd and calculating, and understand their victims' weaknesses and industries.

SocGholish and Zloader – From Fake Updates and Installers to Owning Your Systems
(published: April 25, 2022)
Cybereason researchers have compared trending attacks involving SocGholish and Zloader malware. Both infection chains begin with social engineering and malicious downloads masquerading as legitimate software, and both lead to data theft and possible ransomware installation. SocGholish attacks rely on drive-by downloads followed by user execution of purported browser installer or browser update. The SocGholish JavaScript payload is obfuscated using random variable names and string manipulation. The attacker domain names are written in reverse order with the individual string characters being put at the odd index positions. Zloader infection starts by masquerading as a popular application such as TeamViewer. Zloader acts as information stealer, backdoor, and downloader. Active since 2016, Zloader actively evolves and has acquired detection evasion capabilities, such as excluding its processes from Windows Defender and using living-off-the-land (LotL) executables.
Analyst Comment: All applications should be carefully researched prior to installing on a personal or work machine. Applications that request additional permissions upon installation should be carefully vetted prior to allowing permissions. Additionally, all applications, especially free versions, should only be downloaded from trusted vendors.

What’s With The Shared VBA Code Between Transparent Tribe And Other Threat Actors?
(published: February 9, 2022)
A recent discovery has been made that links malicious VBA macro code between multiple groups, namely: Transparent Tribe, Donot Team, SideCopy, Operation Hangover, and SideWinder. These groups operate (or operated) out of South Asia and use a variety of techniques with phishing emails and maldocs to target government and military entities within India and Pakistan. The code is similar enough that it suggests cooperation between APT groups, despite having completely different goals/targets.
Analyst Comment: This research shows that APT groups are sharing TTPs to assist each other, regardless of motive or target. Files that request content be enabled to properly view the document are often signs of a phishing attack. If such a file is sent to you via a known and trusted sender, that individual should be contacted to verify the authenticity of the attachment prior to opening. Thus, any such file attachment sent by unknown senders should be viewed with the utmost scrutiny, and the attachments should be avoided and properly reported to appropriate personnel.

Fake Windows 11 Upgrade Installers Infect You With RedLine Malware
(published: February 9, 2022)
Due to the recent announcement of Windows 11 upgrade availability, an unknown threat actor has registered a domain to trick users into downloading an installer that contains RedLine malware. The site, "windows-upgraded[.]com", is a direct copy of a legitimate Microsoft upgrade portal. Clicking the 'Upgrade Now' button downloads a 734MB ZIP file which contains an excess of dead code; more than likely this is to increase the filesize for bypassing any antivirus scan. RedLine is a well-known infostealer, capable of taking screenshots, using C2 communications, keylogging and more.
Analyst Comment: Any official Windows update or installation files will be downloaded through the operating system directly. If offline updates are necessary, only go through Microsoft sites and subdomains. Never update Windows from a third-party site due to this type of attack.

S.O.V.A. – A New Android Banking Trojan with Fowl Intentions
(published: September 10, 2021)
ThreatFabric researchers have discovered a new Android banking trojan called S.O.V.A. The malware is still in the development and testing phase and the threat actor is publicly-advertising S.O.V.A. for trial runs targeting banks to improve its functionality. The trojan’s primary objective is to steal personally identifiable information (PII). This is conducted through overlay attacks, keylogging, man-in-the-middle attacks, and session cookies theft, among others. The malware author is also working on other features such as distributed denial-of-service (DDoS) and ransomware on S.O.V.A.’s project roadmap.
Analyst Comment: Always keep your mobile phone fully patched with the latest security updates. Only use official locations such as the Google Play Store / Apple App Store to obtain your software, and avoid downloading applications, even if they appear legitimate, from third-party stores. Furthermore, always review the permissions an app will request upon installation.

Finding Azurescape – Cross-Account Container Takeover in Azure Container Instances
(published: September 9, 2021)
Unit 42 researchers identified and disclosed critical security issues in Microsoft’s Container-as-a-Service (CaaS) offering that is called Azure Container Instances (ACI). A malicious Azure user could have compromised the multitenant Kubernetes clusters hosting ACI, establishing full control over other users' containers. Researchers gave the vulnerability a specific name, Azurescape, highlighting its significance: it the first cross-account container takeover in the public cloud.
Analyst Comment: Azurescape vulnerabilities could have allowed an attacker to execute code on other users' containers, steal customer secrets and images deployed to the platform, and abuse ACI's infrastructure processing power. Microsoft patched ACI shortly after the discl |

NoxPlayer Supply-Chain Attack is Likely The Work of Gelsemium Hackers
(published: June 14, 2021)
ESET researchers have discovered malicious activity dating back to at least 2014 attributed to the Gelsemium cyberespionage group. The group targets electronics manufacturers, governments, religious entities in multiple countries throughout East Asia and the Middle East. Gelsemium demonstrated sophistication in their infection chain with extensive configurations, multiple implants at each stage, and modifying settings on-the-fly for delivering the final payload. The dropper, called Gelsemine, will drop a loader called Gelsenicine that will deliver the final payload, called Gelsevirine.
Analyst Comment: Threat actors are always adapting to the security environment to remain effective. New techniques can still be spotted with behavioural analysis defenses and social engineering training. Ensure that your company's firewall blocks all entry points for unauthorized users, and maintain records of how normal traffic appears on your network. Therefore, it will be easier to spot unusual traffic and connections to and from your network to potentially identify malicious activity. Furthermore, ensure that your employees are educated about the risks of opening attachments, particularly from unknown senders and any attachment that requests macros be enabled.

BackdoorDiplomacy: upgrading from Quarian to Turian
(published: June 10, 2021)
A new advanced persistent threat (APT) group, dubbed BackdoorDiplomacy, has been targeting ministries of foreign affairs (MOFAs) and telecommunication companies located in Africa and the Middle East since at least 2017, according to ESET researchers. The group was observed targeting “vulnerable internet-exposed devices such as web servers and management interfaces for networking equipment.” BackdoorDiplomacy’s objective is to access a system, use pentesting tools for lateral movement, and install a custom backdoor called “Turian,” which is based on the Quarian backdoor.
Analyst Comment: It is important that your company has patch-maintenance policies in place, particularly if there are numerous internet-facing services your company uses or provides. Once a vulnerability has been reported on in open sources, threat actors will likely attempt to incorporate the exploitation of the vulnerability into their malicious operations. Patches should be reviewed and applied as soon as possible to prevent potential malicious activity.

2021-05-21 12:06:56 | Live From RSAC: Anne Neuberger Addresses President Biden\'s Executive Order on Cybersecurity (lien direct) |  Anne Neuberger, Deputy National Security Advisor for Cyber and Emerging Technology, addressed President Biden???s executive order at the virtual RSA Conference this week. The executive order, announced on May 12, 2021, aims to safeguard U.S. cybersecurity and modernize cybersecurity defenses.
As Neuberger explains, this executive order couldn???t come at a more critical time. The Biden administration was challenged with two cybersecurity incidents in the first 100 days ??? SolarWinds and Microsoft Exchange. Note that the session must have been pre-recorded because she didn???t even mention a third attack that disrupted the Colonial Pipeline.
The incidents proved three major lessons:
Adversaries will look for any opening to attack, including the government???s suppliers.
Partnerships are critical. The government needs the private sector, and the private sector needs the government.
The government needs to modernize cybersecurity defenses.
???[These lessons prove that] we need to shift our mindset from incident response to prevention,??? said Neuberger. ???We simply cannot let waiting for the next shoe to drop be the status quo under which we operate.???
In the software development world, we call this being stuck in a ???break/fix??? mentality. It is better to build a software development process that causes less ???breaks.??? That enables you to deliver more software with less failures. We are starting to see cybersecurity learn from software development principals, shifting our cybersecurity problems to the left.
Breaches are more detrimental than most organizations realize. Neuberger noted two staggering statistics. In 2019, Accenture reported an average company spends $13 million per breach. And CIS and McAfee reported that cybercrime cost 1 percent of global GDP in 2018. Organizations are far better off spending the money to secure their applications, including demanding better from their vendors, than waiting for a breach. How many small businesses, schools, hospitals, or government agencies have an extra $13 million to spend on an unexpected breach?
What Neuberger didn???t mention is that that same study from Accenture cited an increase of 67 percent in cyberattacks over the past five years. And if cyberattacks continue at this velocity, Accenture calculates a total value at risk of $5.2 trillion globally over the next five years.
The president???s approach is proactive and includes modernizing cyber defenses, returning to a more active role in cybersecurity internationally, and ensuring that America has a better posture to compete. It was the SolarWinds breach that opened our eyes to the fact that we don???t have modern cyber defenses in place. Software supply chain security is of particular concern.
???The current model of build, sell, and maybe patch means that the products the federal government buys often have defects and vulnerabilities that developers are accepting as the norm with the expectation that they can patch later. Or perhaps they ship software with defects and vulnerabilities that they don???t think merit fixes ??ｦ. That???s not acceptable,??? said Neuberger. ???Security has to be a basic design consideration.??? ﾂ?ﾂ?
Neuberger hinted that the executive order might require federal vendors to build software in a secure development environment. And that software leveraged by the federal government should include strong authentication, encryption and limit privileges. As for preexisting critical infrastructure that was built before the Internet, the orde |
