This chapter has outlined the types of response that organizations are expected to provide against attackers. The previous chapters have discussed the attack life cycle and outlined the tools and techniques that attackers normally come packed with. From these tools and techniques, a life cycle capable of mitigating them was designed. This chapter has discussed an effective vulnerability management life cycle composed of six steps. Each of the steps is aimed at making the life cycle effective and thorough in mitigating the vulnerabilities that may be in an organization that attackers may exploit. The well-planned life cycle ensures that not a single host of an organizational network is left exposed to attackers. The life cycle also ensures that the organization ends up with a fully secured IT environment and that it is hard for attackers to find any vulnerabilities to exploit. This chapter has given a set of best practices for each step of the life cycle. These best practices are aimed at ensuring that the incident response teams and the IT staff members make an exhaustive use of each step to secure the organization. In the next chapter, you will learn about the importance of logs and how you can analyze them.
