The Practice of Network Security Monitoring: Understanding Incident Detection and Response by Richard Bejtlich

Network security is not simply about building impenetrable walls — determined attackers will eventually overcome traditional defenses. The most effective computer security strategies integrate network security monitoring (NSM): the collection and analysis of data to help you detect and respond to intrusions.

In The Practice of Network Security Monitoring, Mandiant CSO Richard Bejtlich shows you how to use NSM to add a robust layer of protection around your networks — no prior experience required. To help you avoid costly and inflexible solutions, he teaches you how to deploy, build, and run an NSM operation using open source software and vendor-neutral tools.

Youll learn how to:

Determine where to deploy NSM platforms, and size them for the monitored networks Deploy stand-alone or distributed NSM installations Use command line and graphical packet analysis tools, and NSM consoles Interpret network evidence from server-side and client-side intrusions Integrate threat intelligence into NSM software to identify sophisticated adversaries Theres no foolproof way to keep attackers out of your network. But when they get in, youll be prepared. The Practice of Network Security Monitoring will show you how to build a security net to detect, contain, and control them. Attacks are inevitable, but losing sensitive data shouldnt be.

The Top SIEM Books You Should Be Reading This Year

Sometimes, the key to technological advancement is decidedly old-school. Security information and event management SIEM is an essential component of any enterprise-level security toolbox—especially as the cybersecurity paradigm shifts from a prevention-based model to a detection model. Making sure your team understands your SIEM solution is a significant and vital hurdle. SIEM does have a reputation, perhaps well-deserved, for being the most complicated of the cybersecurity fields. Your IT security team needs to understand how to manage new capabilities in your SIEM solution in order to best understand how to protect your enterprise. We compiled a short list of the top introductory SIEM books. We tried to keep our selection of SIEM books to within the past 5 years, and that each is its own kind of rewarding reading experience.

Class Objectives

What Else Did the Intruder Do? NSM does not involve preventing intrusions because prevention eventually fails One version of this philosophy is that security breaches are inevitable In fact, any networked organization is likely to suffer either sporadic or constant compromise Your own experience may well confirm this hard-won wisdom IT mainly responsible, security assists But if NSM doesn t stop adversaries, what s the point? I hope that you re excited by the thought that, yes, adversaries can compromise systems, but CIRTs can win if they detect, respond to, and contain intruders before they accomplish their mission But if you can detect it, why can t you prevent it? The simple answer is that the systems and processes designed to protect us aren t perfect Prevention mechanisms can block some malicious activity, but it s increasingly difficult for organizations to defend themselves as adversaries adopt more sophisticated tactics A team can frustrate or resist intrusions, but time and knowledge frequently become the limiting factors Plan Prepare Assess Resolve Escalate Respond Resist Filter Protect Collect Analyze Detect Security mainly responsible, IT assists Figure Enterprise security cycle 2 Security pioneer Winn Schwartau published Time-Based Security in I endorsed the centrality of time as presented in his book in , in my post Where in the World Is Winn Schwartau?

Description Firewalls and antivirus are not enough to protect modern computer networks--abuses and attacks are common and cannot be completely prevented. Instead, networks are now monitored to detect security incidents, and security teams respond to them to limit the harm they cause. This class prepares students for jobs in monitoring and incident response, providing skills that are in high demand. Hands-on projects will include basic configuration and use of Splunk, ELK, and Security Onion--popular network security monitoring solutions. Hardware requirements: Students need a host computer with VMware Player, Fusion, or Workstation installed, at least 30 GB of drive space, and an Internet connection fast enough to download 5 GB of data in a reasonable time. Quizzes Chapter quizzes are available in plaintext and Canvas exports for participants who want them. They will also be available online for those who wish to take them during the class.

In as much as network security monitoring is important to detect threats originating from outside the network, it can also be used to detect threats originating from within. Although half of data breaches are unintentional, the loss of data and financial cost of an internal breach can be significant because, in many cases, the perpetrator knows where to look. Effective network security monitoring with LANGuardian can prevent many insider thefts. Historical data can be analyzed to identify unusual or suspicious fileshare access, and alerts can be set up to warn of specific network activity. LANGuardian includes both a traffic analysis and IDS engine to root out suspicious activity from your on premise or cloud networks. Network security monitoring in this manner is far more effective than individual user logging, as it helps prevent unintentional data breaches as well as those conducted for malicious purposes.
