5 Fundamental Tips to Keep Your Network Safe

Posted on Tue, Oct 9, 2012

Network SecurityThe need for IT security is paramount to successful operations, especially in the business world. All data is important and should not be subject to outside intrusion in the form of malware, worms, spyware, viruses, botnets or adware. Regardless of the size of the organization, an IT management system should be set up in order to protect against intruders.

The IT system should include data backup and a defense system. While most companies are content with having an antivirus, others go the extra mile to install several layers of software and hardware to deter threats from corrupting their networks. Good network management also stops the threat from spreading should it make its way past these defenses.

Besides malware and viruses, other threats to computer networks are attacks from hackers, theft of data, zero hour and zero day attacks, DoS also known as Denial of Service as well as DDoS which is Distributed Denial of Service Attacks. Such threats are quite harmful and deter business continuity because they are interested in exploiting passwords that are weak, wireless networks which are unsecured, unsecure sites, and users who have malicious intent just to mention a few. It is therefore vital that network management is carried out securely.

Below are some 5 tips which will help you secure your network:

1. Create Strong Passwords

An out-of-site password does not guarantee a secure computer. Many sites will consider a strong password one that has 6 or more characters with a combination of numbers, symbols and both upper and lower case letters. Not only should a strong password have the mentioned features, it should not be easy for humans to crack it either. It is recommended that passwords be routinely changed in cycles of 3 months even when using cloud computing. Users should also be trained to recognize tricks that lure them into divulging their passwords. Hackers have a long history of pretending to be IT security or looking at users as they key in the passwords in order to access protected data.

2. Delete Unused Accounts

Accounts which are no longer used must be deleted since they are easy to access. Large organizations cannot monitor all accounts that are inactive, but they can use software to clean up unused accounts. Such software is easily to find especially when using SaaS.

3. Managed Services

Managing access to crucial data by employees is very important. This is because employees who gain access to privileged information may pose as a security threat. A recent survey by Ponemon Institute and HP found that employees could access data which is out of their job level. This information is usually confidential and sensitive; it is therefore prudent to notify the IT department when there are changes in the workplace.

4. Keep Current Updates

Online criminals look for operating systems, web plug-ins, software applications and browsers that are not up to date, or those with patches. It is important to ensure that various programs and devices are regularly updated. IT management should strive to have automatic updates enabled.

5. Keep VPN Secured

Virtual Private Network should be encrypted to ensure that it is secure. Identity authentication should also be secured to ensure that no intruders gain access to the network. Multi-level authentication is usually better and more secure when it comes to authenticating the identity of the user especially when trying to access data on platform such as cloud archiving.

Keeping a business network safe is a must and cannot be ignored or taken lightly. Consider a reputable IT company that can securely manage your network.
