1 IMPLEMENTING A SECURITY ANALYTICS ARCHITECTURE Solution Brief

2 SUMMARY New security threats demand a new approach to security management. Security teams need a security analytics architecture that can handle a much greater volume and wider scope of data than at present, not to mention provide them with tools to lead them quickly to the most pressing issues. They need threat intelligence about the latest tools, techniques, and procedures in use by the attacker community, and the ability to track and manage the responses initiated as a result of the issues they identify. 99 percent of breaches led to data compromise within days or less, whereas 85 percent of breaches took weeks or more to discover Verizon Data Breach Investigations report TRADITIONAL SECURITY ISN T WORKING According to the 2012 Verizon Data Breach Investigations report, 99 percent of breaches led to data compromise within days or less, whereas 85 percent of breaches took weeks or more to discover. This presents a significant challenge to security teams as it grants attackers extended periods of time within a victim s environment. More free time leads to more stolen data and more digital damage. Principally, this is because today s security measures aren t designed to counter today s more advanced threats. Traditional security measures are often: Signature-based: looking for known bad data sequences based upon previous identical attacks Perimeter oriented: concentrating on preventing or detecting threats entering the organization Compliance driven: designed to meet the requirements of auditors, or specific government mandates, rather than addressing the biggest risks to the organization Simultaneously, threats are becoming exponentially more advanced. The threats often seen today are: Agile: they anticipate the means organizations use to protect themselves and use adaptive techniques to evade many common detection and prevention systems Focused: today s threats often have very specific goals, perhaps targeting a narrow class of organization, or even one organization Intelligent: they use a wide range of social engineering techniques and technical exploits to gain a foothold within victim organizations and avoid detection This means that organizations need to start thinking differently about the tools they deploy and the techniques they use to defend themselves. Rapidly Evolving Threats Criminals Petty criminals Unsophisticated Organized crime Organized, sophisticated supply chains (PII, financial services, retail) Nation State Actors PII, government, defense industrial base, IP rich organizations Non-state Actors Terrorists PII, government, critical infrastructure Anti-establishment vigilantes Hacktivists, targets of opportunity page 2

3 TRADITIONAL SIEM HAS BEEN A GOOD START RSA has long been a provider of industry-leading Security Information and Event Management solutions, and believes that traditional SIEM systems have been valuable in providing: Reporting on device activity providing key insights into who, what, where, and when critical activities are taking place Basic alerting on known sequences through correlation rules, that can draw attention to the most egregious or suspicious uses of computing resources Proof of compliance for internal and external auditors through regular reports, created in an automated fashion rather than being manually generated for every audit or assessment Central view into disparate event sources being collected so that security teams can make decisions more rapidly based upon information collected from a number of sources Security teams need to quickly determine how an attack happened, to reduce the attacker free time the time between the attacker entering the environment and being detected in the infrastructure and put measures in place prevent similar future attacks. However, in today s landscape, new requirements need to be taken into account. Attacks now come not just from vandals or amateurs, but from sophisticated, criminal enterprises and even nation states. These attackers deploy advanced techniques such as covering their tracks in log files and minimizing the number of auditable events. As such, traditional SIEM proves insufficient. This requires organizations to take a more advanced approach to countering these threats. ORGANIZATIONS NEED more effective SECURITY MANAGEMENT SOLUTIONS In this world of advanced threats, security teams need to quickly determine how an attack happened, to reduce the attacker free time the time between the attacker entering the environment and being detected in the infrastructure and to put measures in place prevent similar future attacks. Given this, RSA believes organizations need a more effective platform that addresses more security management problems since: Advanced threats require enterprise-wide visibility into network traffic and log event data: neither network traffic data nor log event data alone provides enough information to detect and investigate these types of threats Security is now a Big Data problem for SOC analysts: SOC analysts now need to delve into a much larger, dynamic, and diverse set of data to identify advanced threats which requires the fusion of internal and external intelligence Compromise is inevitable: a realistic goal is not to resist all attacks, but to react fast to mitigate damage and thus minimize the impact on the business RSA Security Management and Compliance Page 3

4 To this end, experienced security practitioners are asking RSA to help them: Collect everything that s happening in my infrastructure. Previous approaches to security have depended on using information about known threats to make decisions about which data to collect about what is happening within the environment. With more agile, advanced threats, making those assumptions ahead of time makes it is likely that when the threat arises, the security teams won t have all the information needed to respond properly. This means that in today s environment, security teams want to collect everything about what is going on. Help me to identify key targets and threats. In a large, complex IT infrastructure, it is difficult to keep track of what each system does and the ways in which it might be attacked. Security teams need a way to interface with the business to identify the most critical information, business processes, and supporting assets, to best assess the threats the organization faces. Enable me to investigate and prioritize incidents. Also in a large, complex IT infrastructure, there are often so many issues to deal with that security teams need more guidance around identifying the most pressing issues, and which ones could have the highest impact to the business. This means having more information about the business context of incidents and the criticality of systems and processes they affect. Enable me to manage those incidents. Responding to incidents can be a tricky affair from assessing the damage, to communication, to remediation and cleanup requiring the coordination of resources across a wide range of teams, both within IT and across the business. Security teams need a way to kickoff and coordinate these activities to minimize the adverse impact on the business. FULL NETWORK VISIBILITY IS A MUST The most advanced threats can be extremely difficult to detect. Often, their most visible footprint is on the network as they enter into the IT environment, propagate throughout and exfiltrate data to its intended destination. As such, full network packet capture is necessary to: Identify malware entering the environment and prioritize actions related to it. Modern malware looks very much like any other file traversing a network, but full packet capture allows organizations to isolate and reconstruct executable files, and automate much of the analysis needed to identify tell-tales signs of malicious intent. This then helps malware analysts prioritize which issues they need to respond to first. Track the lateral movement of an attacker once inside the organization. Once an attacker has a foothold within an organization, they often move laterally from endpointto-endpoint gathering the necessary information to launch the next stage in the attack. Since these endpoints are seldom centrally monitored, full network packet capture is needed to gain visibility into this lateral movement within an organization. Prove exactly what happened and what data was exfiltrated. Many advanced threats will not be detected until the attack is in progress, or even after it has been completed. At this point, security teams need to be able to assess the damage by reconstructing the attack and determining what data, if any, has left the organization, and whether it was encrypted or not.
