What is the difference between network security and data security?

With Cyber Security being a top priority for many SMEs in 2020, there has been a raft of blogs and white papers advising what we should be doing to protect ourselves and our businesses from Cyber-attack.

In order to fully protect your business, CJAZ believe it's important to understand the 2 main types of security and the corresponding breaches that could happen in each scenario. By understanding the two main types of threat that exist, you can then ensure that your business is protected from them both.

The two main types of security are:

1. Network Security 2. Data Security

What is Network Security?

Basically, Network Security is protection of the access to files and directories in a computer network against hacking, misuse and unauthorised changes to the system. An example of network security is an anti-virus system.

Common Network Security threats

When you encounter a network security breach it is usually in the form of a program or virus that has been created by hackers to break into your network and corrupt or steal your data.

Common network security threats include:

  • Malware

  • Viruses

  • Spyware

  • Adware

  • Trojan horses

  • Worms

  • Phishing

  • Wifi attacks

  • Denial of service (DOS) attacks

How do I protect my network?

There are many measures that you can put in place to protect your network, here are a few of the most common ones:

  1. Install and monitor your Firewall performance.

  2. Install and monitor anti-malware software

  3. Implement network encryption

  4. Keep your network up to date

What is Data Security?

Data security is a set of standards and technologies that protect data from intentional or accidental destruction, modification or disclosure.

Common data breaches include:

  1. Weak, default or stolen passwords

  2. Accidentally shared sensitive information

  3. Non-approved SaaS (software as a service)

  4. Data leakage, most often (90%) caused by user mistakes

  5. Loss or theft of unencrypted device

How do I protect my business from data breach?

Over 80% of hacking-related breaches leveraged weak, default or stolen passwords. Therefore, the best way to prevent data breach, is by ensuring passwords are strong enough and used every time a device is used. The best way to do this at the moment is to use two-factor authentication. Put simply, two-factor authentication is the simplest, most effective way to make sure users really are who they say they are.
