The Critical Security Controls and the StealthWatch System
Jan 15, 2015
As today’s cyber-attackers become more sophisticated and nefarious, organizations must adopt the right mix of conventional and next-generation security tools to effectively defend their infrastructure from advanced threats. The Critical Security Controls effort is a growing movement that has been helping government agencies and large enterprises prioritize their cyber security spending accordingly.
By leveraging NetFlow and other types of flow data, Lancope’s StealthWatch System delivers continuous network visibility to fulfill a number of the highest priority controls, enhancing timely detection of targeted threats and improving incident response.
Learn the latest about the Critical Security Controls and hear how the StealthWatch System fits in.

Presentation Notes
Targeted attacks aim to achieve a specific impact against specific enterprises, and have three major goals: Denial of service: disrupting business operations Theft of service: obtaining use of the business product or service without paying for it Information compromise: stealing, destroying or modifying business-critical information The motivation is usually financial gain, such as through extortion during a denial-of-service attack, trying to obtain "ransom" for stolen information, or selling stolen identity information to criminal groups. Although, recently, we have seen a rash of disclosures as companies publicly announce losses of customer-sensitive data, most targeted attacks do not get any publicity because enterprises do not want to expose the extent of the damage an attack may have caused. Targeted attacks can use custom-created executables that are rarely detected by signature-based techniques. To be successful, such attacks generally require some means of communication back to an outside party, whether out of band — as when an insider puts information onto removable media and physically carries it outside of enterprise control — or in band — as when Internet mechanisms are used.

Presentation Notes
Gartner's vulnerability management life cycle defines the operational processes and technologies that are needed to discover and remediate security weaknesses before they are exploited. Policies that define a secure IT infrastructure are used as the reference for a baseline to discover vulnerabilities and security configuration policy compliance issues. Security weaknesses should be assessed with respect to the vulnerability, the current threat environment and the business use of the asset to to prioritize the shielding and remediation tasks that follow. Remediation is facilitated through cross-organizational processes and workflow. Remediation activity is also driven through monitoring of privileged user access, of compliance with technical controls and for new vulnerabilities. Vulnerability management operationally implements a subset of the controls that are defined within a security program. The life cycle implements many of the basic security controls that auditors seek when evaluating compliance. Organizations that take the extra step of mapping the policies that are implemented by vulnerability management to control standards and best practices can strengthen their posture with auditors and reduce the cost of compliance reporting through automation. Action Item: Link vulnerability management and compliance projects to ensure that compliance spending results in lower security operations costs and a more secure environment. Action Item: IT security organizations must work with IT operations to develop and implement the operational processes that are needed for effective vulnerability mitigation.
