A network is simply a way for devices like computers, phones, or servers to connect and communicate with each other. It is similar to a road system that allows cars to travel between different places. If we take the cars as data and the destinations as devices, we need to make sure there are no obstacles in the roadway i.e. network. To ensure a smooth passage we need to ensure that there are no loopholes or bugs in an organization’s network. Hence, your organization would need a regular network security audit.

Network Security Audit – A Brief Overview

A network audit carefully checks the security of your IT infrastructure based on the set regulations by regulatory authorities that are mandatory based on the nature of your organization. There are three important aspects around which the security audit is performed. These are network infrastructure, network devices, and network management.

A network security audit makes sure there are no vulnerabilities hidden in your network that are potential threats. The audit also includes a detailed review of the organization’s security mechanisms which are in place to protect the devices and the overall network infrastructure. It ensures that all the devices within your organization’s network that are connected to the internet are safe and all possible loopholes are informed to the respective IT team for patching with recommendations.

Importance of Regular Network Security Audit

Regular security audits from cybersecurity experts like Kratikal help organizations strengthen their network security, prevent cyber threats, and ensure smooth and secure operations. Here are a few reasons why every organization should conduct regular security audits on a regular basis:

Identifies Security Gaps

The masterminds behind cyberattacks are constantly on the lookout for weaknesses in an organization’s network. Therefore, regular network security audits help detect and fix security gaps before they can be exploited. By proactively addressing vulnerabilities, organizations can prevent financial losses, data breaches, and reputational damage, strengthening their overall cybersecurity posture.

Prevents Data Breaches

Data breaches come with a cost. It can lead to financial loss, reputational damage, and legal consequences that can bring your organization straight to ground zero. Therefore, network audits performed regularly helps prevent unauthorized access to sensitive data by strengthening security measures.

Ensures Compliance with Regulations

To ensure organizations keep their data secure, there are some set standards and regulations that an organization needs to abide by to ensure the security of confidential data. Many industries have strict data protection laws, such as GDPR, DPDP, and ISO 27701. Regular security audits help identify whether organizations comply with these regulations or not. The consequences of non-compliance are hefty and a network audit keeps you safe from that zone.

Improves Network Performance

A security audit not only enhances safety but also helps optimize network performance by identifying inefficiencies and potential bottlenecks. During the audit, security loopholes and misconfigurations are detected, but at the same time, issues like slow network speeds, overloaded devices, and outdated hardware can also be identified. By addressing these problems, organizations can improve both security and efficiency, ensuring a faster, more reliable, and well-protected network.

Builds Customer Trust

Customers trust organizations that prioritize security because they want to know their personal and financial data is safe. Regular network audits show that a company is sound when it comes to cybersecurity and prioritizes identifying and fixing vulnerabilities. This commitment to security builds credibility, enhances brand reputation, and strengthens customer loyalty.

Reduces Downtime and Financial Losses

Security incidents are sudden and instant. It can lead to major operational disruptions and financial losses. Not only that, it gradually diminishes an organization’s ability to function smoothly in no time. Cyberattacks such as ransomware, data breaches, and DDoS attacks are common and have adverse effects. It can bring systems down, halt critical operations, and result in costly recovery efforts. Regular security audits help identify vulnerabilities, strengthen defenses, and actively address risks before they escalate into full-blown security incidents.

How is a Security Audit for a Network Performed?

The infographic below provides an overview of how network security audit is performed:

The step-by-step explanation is listed below:

Step 1: The audit process for network security commences with identifying all devices connected to the network, such as routers, switches, and firewalls. It also ensures that nothing is left unmonitored. 

Step 2: Next, the auditor evaluates the network policies to check if access controls, password policies, and firewall rules are properly configured and up to date. 

Step 3: Once the policies are reviewed, a risk assessment is conducted. This is done to identify potential security gaps, such as weak passwords, outdated software, or vulnerable systems. 

Step 4: To further test the network’s defenses, network penetration testing is performed, where security analysts simulate attacks to find weaknesses before real hackers do. 

Step 5: Finally, a detailed report is created, summarizing the findings, highlighting security risks, and providing recommendations to fix them. 

Who Can Perform a Network Security Audit?

The term security audits is synonymous with internal audits. For organizations that do not have an IT Security Team, they need to get in touch with external auditors. VAPT and security service providers like Kratikal can help SMEs and large enterprises perform such audits. Also, it is advised for large organizations to conduct their network audit externally instead of having their team to avoid any scope of discrepancies in ensuring the security of their network.

By preventing unexpected cyberattacks, security audits for network help reduce downtime, maintain productivity, and ensure seamless business operations. This not only saves organizations from potential financial losses but also protects their reputation and customer trust. A well-audited and secure network ensures business continuity, allowing organizations to operate efficiently without fear of disruptions caused by cyber threats. In industries handling sensitive information, such as banking, healthcare, and e-commerce, demonstrating strong cybersecurity practices can also provide a competitive advantage, attracting more customers and partners who value security. 

Do not let your network get infected to the point of no return, a network security audit is the friend you need to avoid the impending crisis!
