Question
A company has identified a number of vulnerable, end-of-support systems with limited defensive capabilities. Which of the following would be the first step in reducing the attack surface in this environment?
A. Utilizing hardening recommendations
B. Deploying IPS/IDS throughout the environment
C. Installing and updating antivirus
D. Installing all available patches
Answer
A. Utilizing hardening recommendations
Explanation
When dealing with vulnerable, end-of-support systems that have limited defensive capabilities, the first step in reducing the attack surface should be to utilize system hardening recommendations and best practices. System hardening involves securing the configuration of the operating systems and applications to reduce vulnerabilities and potential attack vectors.
Hardening steps may include:
- Disabling unnecessary services, protocols, and ports
- Removing or disabling unneeded software and user accounts
- Implementing strong password policies and access controls
- Configuring logging and auditing to detect suspicious activity
- Applying the principle of least privilege for user permissions
- Segmenting the vulnerable systems from other parts of the network
While the other options like deploying IPS/IDS, updating antivirus, and installing available patches are also important defensive measures, they should come after the initial system hardening. Hardening helps lock down the inherent vulnerabilities in the outdated, unpatched systems. The other controls add layers of defense on top of the hardened configuration.
So in summary, utilizing hardening recommendations is the crucial first step because it directly reduces the attack surface of the vulnerable end-of-support systems themselves. This makes it more difficult for attackers to gain an initial foothold. The hardened systems then serve as a more secure foundation on which to layer additional defensive tools and patch management.
