Attacks can come in many forms like viruses, worms, trojans, spam, adware, malware and phishing. Hackers intentionally access computer resources without authorization. Denial-of-service attacks overload servers to deny users access. While early hackers were curious, today's criminals dominate attacks. On the horizon, cyberterrorism and cyberwarfare from governments could cause widespread damage. Security is primarily a management issue involving risk analysis and comprehensive protection across assets, access control, firewalls, intrusion detection/prevention systems, and host hardening through vulnerability testing.

AttackersTraditional hackers were curiosity driven.Today’s hackers are criminals that dominate the attack world.On the horizon, cyberterror attacks by terrorist and cyberwar attacks by foreign governments could cause unprecedented levels of damage.
Security ManagementSecurity is primarily a management issue, not a technical issue.Risk Analysis – balancing cost and benefits of protectionComprehensive Security – Closing all avenues of attacks
Access ControlIdentify and list each assetRate the sensitivity of each asset in terms of security riskAccess Control Plan. Also called Triple AAA. Authentication, Authorization, and Auditing
Firewalls, IDSs, and IPSsFirewalls examine packets passing through the firewall.Intrusion Detection Systems (IDS) are designed to detect suspicious traffic.Intrusion Prevention Systems (IPS) are used to recognize complex attacks. It helps prevent false positives.
Host Hardening and Vulnerability TestingServers can be hardened by having vulnerabilities patchedVulnerability Test should be conducted by attacking the network (with permission) , in order to identify security weaknesses.http://www.youtube.com/watch?v=MJNJjh4jORY
