Know how secure is your company’s Intranet 

When the topic of intranet security is brought up in the office, it is frequently received with repressed yawns or glazed eyes. Because it’s an internal network, there’s a common misconception that the intranet site is immune to viruses and hacking. Intranet security, on the other hand, extends beyond external threats. Intranet security also includes ensuring that the correct people have access to the right information.

So, let’s Discuss the essentials of intranet security

External Threats to Intranet Security

Even though the intranet is a closed, private network, it is nevertheless vulnerable to external dangers such as worms, viruses, and malware from hackers or malicious software.

Threats to Network Security

To protect against external threats, it’s recommended to employ a firewall. A firewall is a security barrier that separates the intranet from the internet. It’s a software program or a hardware device that filters data coming in from the internet and sends it to the intranet. Based on the guidelines, which might be pre-configured or set with the aid of the firewall administrator, firewalls can also prefer to allow or prohibit community conversation between gadgets.

Firewalls protect against various online threats, and while they can’t protect against everything, they’re an essential first line of defense.

Breach of Security

The intranet may face suspicious traffic such as spam, phishing, spyware, or malware from time to time. This suspect traffic can be blocked using an excellent email filter and firewall.


The majority of businesses are aware that anti-virus software is required. However, because the threat posed by viruses is continuously evolving, you must keep your software up to date.

There are a variety of internal dangers to intranet security that must be addressed in addition to exterior threats.

Internal Threats Weak Passwords Intranet Security

Users frequently use weak passwords, share them with coworkers, never change them, and even write them down or tape them to their computers! Employees should be expected to update their passwords regularly (every 60 days should be standard) and use passwords that are at least eight characters long and contain a combination of letters, numbers, and keyboard symbols.

Firewalls defend against a wide range of online dangers, and while they can’t protect you from everything, they’re a crucial first line of defense.

Security Vulnerability

The intranet may encounter dubious traffic such as spam, phishing, spyware, or malware from time to time. With a good email filter and firewall, this suspicious traffic can be stopped.

Controlling Access

Is the correct information being accessed by the right employees? Brian in Sales should not have access to confidential boardroom documents. Jenny in Marketing, for example, should not have access to employee salary information. Information access can be restricted on the intranet using a set of file and page permissions. Permissions may be assigned to users primarily based on their activity name, group role, or geographic region – something is suitable for the facts.

This is complemented by the requirement to check permissions regularly. There have been situations where individuals gained access to critical information through a job role they held ten years ago! Employees who have left the company must also have their access removed as quickly as possible.


Turning data into an unrecognizable (encrypted) form is known as encryption. It’s widely used to keep sensitive information secure so that only authorized individuals can see it. Secure Socket Layer (SSL) is a widely used encryption security technique utilized by millions of businesses worldwide, especially online shopping. When you see HTTPS at the start of a website’s address, you know your connection is encrypted and secured with SSL.

Encryption safeguards critical corporate documents and data. So you can be assured that the R&D program, which contains the most up-to-date product information and improvements, is safe from illegal access on the network.

Access from afar

Personnel running on the street or from domestic are more and more the use of intranets outdoor of the traditional workplace environment. Workers frequently do it on their smartphones, tablets, or other mobile devices. Extra precautions must be taken to ensure security when it comes to remote access.

Employees should be required to install the newest anti-virus software and potentially even a personal firewall on their own devices that they use to access the intranet as a minimum security safeguard.

Additionally, workers accessing the intranet via a public 3G, 4G, or Wi-Fi network may expose company information and data to hackers or interception. What about the risk of losing or stealing an employee’s mobile device?

However, there are several steps that may be taken to reduce the dangers. Secure extranet access technologies, such as SSL, VPN (Virtual Private Network), and Firewall Software, can guard against security threats and unauthorized interception, as well as virus attacks.

Furthermore, solutions such as automated time-outs and stopping the device from saving log-in data are more simple approaches to reduce the hazards.
