What’s lurking out there this week?

It’s fair to say every business feels a sense of dread when it comes to the possibilities of cyberattacks and the subsequent business interruptions.

Protecting your information can definitely be a daunting task. The evolution of technology combined with the sophistication of cyberthreats has resulted in an increase in breaches across organizations of all sizes.

So what do you need to know to help reduce your risk of exposure? You can start with a basic understanding of the core components of enterprise security:

Network Security

This over-arching term describes the policies and procedures you implement to avoid and keep track of unauthorized access, exploitation, modification, or denial of the network and network resources. Well-implemented network security helps block viruses, malware, and hackers from accessing or altering information you want to protect.


Your firewall is in many ways your first line of defense. A firewall acts as a barrier between a trusted network and other untrusted networks, including the Internet as well as less-trusted networks such as a retail merchant’s network outside of a cardholder data environment. Firewalls can be implemented in both hardware and software, or a combination of both.

Network Access Control 

Network Access Control (NAC) aims to do exactly what the name implies: control access to a network with policies for pre-admission endpoint security checks and post-admission controls over where your users and their devices can go on a network – and what they can do once there.

Unified Threat Management 

Unified threat management (UTM) is an approach to security management that allows your IT administrator to monitor and manage a wide variety of security-related applications and infrastructure components through a single management console. Designed to protect users from blended threats while reducing complexity, UTM combines elements such as firewall, gateway anti-virus, and intrusion detection and prevention capabilities into a single platform.

Backup and Restore

Yes, it may sound basic but backup and restore is a crucial part of every enterprise security plan. Your approach can include a combination of manual and automated procedures designed to restore lost data in the event of hardware or software failure. Systematic backup of files, databases, and logs of computer activity is part of any recovery and restore procedure.

Many components come together to help protect your business

Now that we’ve got the basics covered, you’re ready to move ahead with an enterprise security strategy that will incorporate multiple layers of security across many applications, devices, networks, and platforms. Firewall security. Threat management. Web security. Email security. Data security. Security incident reporting and proactive planning. All of these come together to help you reduce your exposure from malicious attacks.
