Security management is the process of developing a comprehensive data protection plan. It takes into account all potential threats, the existing network environment, the future needs of the organization, and lays out a multi-tiered blueprint to integrate the security technology needed to combat these threats.
Securing your network begins at the gateway, also called the perimeter, to keep unauthorized users, viruses and malicious code from entering. 
In today's business climate, companies provide network and data access to remote and mobile employees as well as outside vendors. In doing so, companies open themselves up to significant risk. 
In addition to internal security policies, corporate governance and regulatory bodies continually impose new regulations and policies that companies must follow or face stiff penalties. CDW Security Education Center

Trying to secure laptops, cell phones, PDAs, and other mobile devices today is "terrifying," says Christopher Paidhrin, IT security and HIPAA compliance officer at Southwest Washington Medical Center. "End-point security is scarily immature."

- The Elements of Endpoint Security Your IT endpoints, the notebook computers and desktops your people use every day, are probably the weak point in your security program. A four-part protection strategy, none of it very expensive, can help keep you safe.
- Gateway Security The number of malicious attacks trying to get through your network gateway will likely increase every year, and the attacks are becoming more sophisticated. Fortunately, defenses are also becoming more sophisticated.
- Securing the Network Take precautions to keep your business network safe from threats.
- Browsing behavior are major security risks Without knowing it, your users are unlocking doors to your network every day with their browsers. There are effective and inexpensive things you can do to reduce the risk.
- Making the case for security spending Management wants to know the return on investment. But when it comes to security, there are more practical and realistic ways to decide what to spend.
- New responses to network threats There are more threats to your network security than ever before, and traditional defenses are falling behind. There's no such thing as absolute security, and there are no new, silver-bullet security solutions. However, many security technologies that have been around for years have evolved and can help you lower the risk of a successful attack.
