2018-12-12 14:00:00 | New AlienVault and AT&T Cybersecurity Consulting Solution for Cyber Risk and Compliance Management (lien direct) |
Let’s face it, managing cyber risk and compliance is hard. Many organizations struggle to gain the visibility needed to truly understand their overall cyber risks. They also struggle to maintain that visibility as they take on digital business transformation and new cloud computing initiatives. It’s no easy task for organizations to continually align their security priorities to changes in the regulatory landscape, their IT environment, and an always-shifting threat landscape, especially for organizations with limited IT resources.
That’s why we are excited to announce a new solution to help organizations of any size to help reduce their cyber risks and simplify their journey to work toward compliance. Together, AT&T Cybersecurity Consulting and AlienVault, an AT&T Company, are bringing together the people, process, and technology in one unified solution to help organizations improve cyber risk and compliance management. In doing so, we’re making it simple and fast for organizations to consolidate their requirements and to accelerate their security and compliance goals. Download the solution brief to learn more.
“Managing cyber risk and compliance requires an ongoing review of your IT assets and data, security practices, and personnel — and no single security tool provides that holistic visibility,” said Russell Spitler, SVP of Product for AlienVault, an AT&T company, “With a unified solution from AT&T Cybersecurity Consulting and AlienVault, we can help organizations to reduce the complexity and cost of having to juggle multiple products and vendors.”
This solution addresses many of the most challenging aspects of meaningful risk reduction (i.e. you are actually making progress in reducing risks, not simply “managing risks,”) and maintaining continuous compliance. The solution includes: risk assessment, scanning and remediation vulnerability assessment, employee cybersecurity awareness training, continuous network monitoring for the latest threats, and reporting for compliance as well as for internal policy. It is ideal for organizations that are getting started with or want to accelerate their efforts for PCI DSS or HIPAA, but also for non-compliance organizations that are looking to evaluate and improve their cyber risk posture quickly and efficiently.
Unlike other solutions for cyber risk and compliance that are often oversized and do not adapt to an organization’s existing security model, AlienVault and AT&T Cybersecurity Consulting offer flexible options that allow any organization to tailor-fit a solution to their unique environment, business goals, and budget. The solutions include:
Risk-based Cyber Posture Assessment led by AT&T Cybersecurity Consultants
ASV-provided External Vulnerability Scanning Services from AT&T Consulting Services
AlienVault USM Anywhere - a unified platform for threat detection and response
AT&T Cybersecurity IQ Training - cybersecurity user training and assessments
For more details on the products and services included in this solution, read the solution brief here >
Following AT&T Business’ acquisition of AlienVault in August, this offering is the first to combine the phenomenal threat detection and incident response capabilities of AlienVault USM Anywhere and AlienVault Labs Threat Intelligence with the world-class expertise of AT&T Cybersecurity Consulting.

2018-11-25 15:48:54 | The Origin of the Term Indicators of Compromise (IOCs) (lien direct) |  I am an historian. I practice digital security, but I earned a bachelor's of science degree in history from the United States Air Force Academy. (1)Historians create products by analyzing artifacts, among which the most significant is the written word.In my last post, I talked about IOCs, or indicators of compromise. Do you know the origin of the term? I thought I did, but I wanted to rely on my historian's methodology to invalidate or confirm my understanding.I became aware of the term "indicator" as an element of indications and warning (I&W), when I attended Air Force Intelligence Officer's school in 1996-1997. I will return to this shortly, but I did not encounter the term "indicator" in a digital security context until I encountered the work of Kevin Mandia.In August 2001, shortly after its publication, I read Incident Response: Investigating Computer Crime, by Kevin Mandia, Chris Prosise, and Matt Pepe (Osborne/McGraw-Hill). I was so impressed by this work that I managed to secure a job with their company, Foundstone, by April 2002. I joined the Foundstone incident response team, which was led by Kevin and consisted of Matt Pepe, Keith Jones, Julie Darmstadt, and me.I Tweeted earlier today that Kevin invented the term "indicator" (in the IR context) in that 2001 edition, but a quick review of the hard copy in my library does not show its usage, at least not prominently. I believe we were using the term in the office but that it had not appeared in the 2001 book. Documentation would seem to confirm that, as Kevin was working on the second edition of the IR book (to which I contributed), and that version, published in 2003, features the term "indicator" in multiple locations.In fact, the earliest use of the term "indicators of compromise," appearing in print in a digital security context, appears on page 280 in Incident Response & Computer Forensics, 2nd Edition. From other uses of the term "indicators" in that IR book, you can observe that IOC wasn't a formal, independent concept at this point, in 2003. In the same excerpt above you see "indicators of attack" mentioned.The first citation of the term "indicators" in the 2003 book shows it is meant as an investigative lead or tip: |

What is a WEP Key?
Wired Equivalent Privacy (WEP) is a security algorithm for IEEE 802.11 wireless networks. Introduced as part of the original 802.11 standard ratified in 1997, its intention was to provide data confidentiality comparable to that of a traditional wired network.[1] WEP, recognizable by its key of 10 or 26 hexadecimal digits (40 or 104 bits), was at one time widely in use and was often the first security choice presented to users by router configuration tools.

2018-11-19 14:00:00 | Is the Internet of Things Threatening Your Company\'s Security? (lien direct) |
The internet of things (IoT) is changing nearly every industry. Smart devices that can collect and process data, and even make decisions based on that data, though artificial intelligence promises to disrupt business as we know it for years to come.
However, there are some legitimate concerns. The more connected devices your company has, the more potential vulnerabilities are out there. As business owners we want to be able to access the data we collect through the IoT, but we also need to be able to protect that data, and we bear the responsibility for keeping that data secure.
This, like many areas of business, is a time for brutal honesty. If you have vulnerabilities, you need to fix them. You don’t want to be part of the headlines about companies who acted too late or not at all. Your security must adapt to the IoT, and it needs to do so now.
Is the internet of things threatening your company’s security? There are a few questions you will need to ask yourself and your IT department to truly determine the answer:
How do I know?
Most experts agree that the weakness in any network is the devices that make up the IoT. For example, if you have smart light bulbs in your home, they are likely controlled by a hub which not only provides you with more flexibility in controlling them, but also provides security so they do not become a weak point in your network.
This is why an intrusion detection system (IDS) is so important. Technologies from companies like AlienVault allow you to monitor for threats and even give you advice on how to prevent harm from them. Remember there is more than one area of vulnerability in any system. Cloud-based IDS, network IDS, and host-based IDS, along with file integrity management systems, are all essential parts of your strategy.
These alerts tell you there is an attack and can even reveal threats to you, which allows you to put remediation and prevention strategies in place. But what are the threats you should be aware of?
What are the threats?
Why don’t we have houses that are completely smart and controlled by IoT devices? What about our cars? Part of the reason is that a hacker with the right tools could potentially take over control of a house or even a connected car from the owner or driver. For example, the Bangladesh National Bank lost $81 million due to an IoT-based attack.
What are these types of attacks? There are actually several, and they mirror other types of cyberattacks.
Distributed Denial of Service (DDoS): Chrysler/Jeep was vulnerable to this type of attack. Essentially, control of devices or a system is taken by a hacker. Sometimes this comes with ransomware, where the owner or user has to pay to get that control back.
Malware: IoT devices can be used by an attacker to spread malware, sometimes to more than one devic |

Whether you need to monitor hosts or the networks connecting them to identify the latest threats, there are some great open source intrusion detection (IDS) tools available to you.

IDS Detection Techniques
There are two primary threat detection techniques: signature-based detection and anomaly-based detection. These detection techniques are important when you’re deciding whether to go with a signature or anomaly detection engine, but vendors have become aware of the benefits of each, and some are building both into their products. Learning their strengths and weaknesses enables you to understand how they can complement one another.
Signature-based IDS Tools
With a signature-based IDS, aka knowledge-based IDS, there are rules or patterns of known malicious traffic being searched for. Once a match to a signature is found, an alert is sent to your administrator. These alerts can discover issues such as known malware, network scanning activity, and attacks against servers.
Anomaly-based IDS Tools
With an anomaly-based IDS, aka behavior-based IDS, the activity that generated the traffic is far more important than the payload being delivered. An anomaly-based IDS tool relies on baselines rather than signatures. It will search for unusual activity that deviates from statistical averages of previous activities or previously seen activity. For example, if a user always logs into the network from California and accesses engineering files, if the same user logs in from Beijing and looks at HR files this is a red flag.
Both signature-based and anomaly-based detection techniques are typically deployed in the same manner, though one could make the case you could (and people have) create an anomaly-based IDS on externally-collected netflow data or similar traffic information.
Advantages and Disadvantages
Fewer false positives occur with signature-based detection but only known signatures are flagged, leaving a security hole for the new and yet-to-be-identified threats. More false positives occur with anomaly-based detection but if configured properly it catches previously unknown threats.
Network-Based IDS (NIDS)
Network-based intrusion detection systems (NIDS) operate by inspecting all traffic on a network segment in order to detect malicious activity. With NIDS, a copy of traffic crossing the network is delivered to the NIDS device by mirroring the traffic crossing switches and/or routers.
A NIDS device monitors and alerts on traffic patterns or signatures. When malicious events are flagged by the NIDS device, vital information is logged. This data needs to be monitored in order to know an event happened. By combining this information with events collected from other systems and devices, you can see a complete picture of your network’s security posture. Note that none of the tools here correlate logs by themselves. This is generally the function of a Security Information and Event Manager (SIEM).
Snort
Ah, the venerable piggy that loves packets. Many people will remember 1998 as the year Windows 98 came out, but it was also the year that Martin Roesch first released Snort. Although Snort wasn't a true IDS at the time, that was its destiny. Since then it has become the de-facto standard for IDS, than |
