When mentioned in the office, the intranet security issue is greeted with muffled looks and gorged eyes. There is an underlying assumption that intranet is safe from attacks, hacking, and viruses since it is internally used. The security of intranet transcends any external threats. A company needs to ensure that certified staffs are allowed to access the correct information as this also affects the security of the office intranet.
External threats for the intranet security
The intranet is a private and closed network. In spite of this, intranet is vulnerable to cyber criminals especially hackers and other software that bear malicious threats in the form of malware, viruses, and worms. This article examines some of the external threats that the intranet faces and how they can be curbed.
Security threats on the network
External threats are best covered by the use of firewall. A firewall acts as a defensive cover between the internet and intranet. A firewall is a hardware device or a software program that is able to filter information that flows to the intranet. Based on some preconfigured rules and guidelines given by the administrator, firewall may block or allow the flow of traffic between several devices. Firewalls acts as security on several threats that are from the internet. We may not say that firewalls are the best defense, but it suffices to say that firewalls are a good point of defense.
Breaches in security
It is possible for the intranet to experience little traffic that is suspicious. This may include malware, phishing, spam, and spyware. A properly set filter of emails coupled with a firewall will block the unwanted traffic.
Almost every business entity or organization needs to install software that defends its software from viruses. That is anti-virus software. Virus threats are changing day in day out. In view of this, you should ensure that you constantly update your anti-virus software to the current version.
There are some internal threats that you should address too. Some of them are:-
Most of the staffs that are used to working on one computer have very weak passwords. They may even share the passwords with their fellow staffs, and they seldom change them. Some employees go to a further step of writing the passwords on a piece of paper and pinning it near their desks. The Information Technology manager should ensure that employees are prompted to change their passwords after every two months (recommended timeline). Moreover, the passwords should be limited in length, and they should have special characters, numbers and letters.
Accessing information remotely
Remote office access is a common happening across many organizations. This is done mostly by the staffs who work from home, and they do so from their personal computers, phones, tablets, and other devices. The organization should follow to ensure that the devices that access the intranet are fitted with anti-virus software. Moreover, any worker who accesses the company intranet using 4G, 3G or Wi-Fi is automatically exposing the company to risk. The passwords should not be saved on the devices and there should be automated time-outs.
