Define prevention procedures. Detection and analysis Define the threat vector, analyze and implement tools for log and error correlation. Incident Response 25 Containment, eradication, and recovery After an incident has been detected, it must be contained before it can spread. All containment strategies should also include steps to eradicate the threat and vulnerabilities, or at least mitigate them, and steps to recover operating systems, hardware components, and productive time. Post-incident activity A crucial step, document what happened and how it was mitigated.
Pharming Pharming is an attack aimed at redirecting the traffic of a website to another website. Such attacks are usually conducted by exploiting a vulnerable Domain Name System (DNS) server. Man-in-the-middle attacks In a man-in-the-middle attack, a hacker positions himself between a user and the destination. The actual implementation can be carried out in a variety of ways, including using network packet sniffers or altering routing and transport protocols. This type of attack is used for session hijacking, theft of information, sniffing and analyzing network traffic, corrupting data flows, propagating bogus network information, and for DoS attacks.
Granular trust relationships between compartments would mitigate attacks that try to gain a foothold in lower-security domains to exploit high-value assets in higher-security domains. Least privilege Principle applies a need-to-know approach to trust relationships between security domains. This results in restrictive policies, where access to and from a security domain is allowed only for the required users, applications, or network traffic. Everything else is denied by default. Weakest link Architecture uses a layered approach to security, with weaker or less-protected assets residing in separated security domains.
