However, if the data center has advanced fire suppression systems and hot standby backups at another physical location, the risk to the data is minimal. When you make plans to address vulnerabilities, consider the varied types of vulnerabilities. For example, consider the following broad categories of vulnerabilities: ■ Physical vulnerabilities, such as fire, earthquake, or tornado ■ Weaknesses in a system’s design ■ Weaknesses in the protocol(s) used by a system Understanding the Methods of Network Attacks ■ Weaknesses in the code executed by a system ■ Suboptimal configuration of system parameters ■ Malicious software (for example, a virus) ■ Human vulnerabilities (whether intentional or unintentional) For example, consider human vulnerabilities.
External Threats Because external attackers probably do not have intimate knowledge of a network, and because they do not already possess access credentials, their attacks tend to be more technical in nature. For example, an attacker could perform a ping sweep on a network to identify IP addresses that respond to the series of pings. Then, those IP addresses could be subjected to a port scan, in which open services on those hosts are discovered. The attacker could then try to exploit a known vulnerability to compromise one of the discovered services on a host.
As a result, rather than deploying a single security solution, Cisco recommends multiple, overlapping solutions. These overlapping solutions target different aspects of security, such as securing against insider attacks and securing against technical attacks. These solutions should also be subjected to routine testing and evaluation. Security solutions should also overlap in a way that eliminates any single point of failure. Understanding the Methods of Network Attacks Defense in Depth is a design philosophy that achieves this layered security approach.
