What's cyber security?

Computer security, cybersecurity or information technology security (IT security) is the security of computer systems in the theft of or damage to their own hardware, applications, or digital information, in addition to in the disruption or misdirection of their solutions they supply. The area is becoming more important because of greater reliance on computer technologies, the web and wireless system standards like Bluetooth and Wi-Fi, and as a result of development of "smart" devices, such as televisions, smartphones, and the numerous devices which constitute the"Internet of things". Due to its complexity, both regarding science and politics, cybersecurity can also be one of the significant challenges in the modern world.

What's cyber security?

Organizations face many threats to their data systems and information. Knowing all of the fundamental elements to cyber safety is the first step to fulfilling these threats.

Types of cyber security.

The reach of cyber protection is broad. The core regions are explained below, and some other fantastic cyber security plan must take all of them into consideration.

Critical infrastructure includes the cyber-physical systems which society is based on, for example, electricity grid, water purification, traffic lighting and hospitals. Plugging a power plant to the world wide web, as an instance, makes it vulnerable to cyber attacks. The solution for associations accountable for critical infrastructure would be to carry out due diligence to safeguard recognize the vulnerabilities and protect from them. Everyone else must evaluate the way an attack on critical infrastructure that they rely on could impact them and develop a contingency plan.

Application security (AppSec), especially web application security, has become the weakest technical point of attack, but few organizations adequately mitigate all the OWASP Top Ten web vulnerabilities. AppSec begins with secure coding practices, and should be augmented by fuzzing and penetration testing. Rapid application development and deployment to the cloud has seen the advent of DevOps as a new discipline. DevOps teams typically prioritize business needs over security, a focus that will likely change given the proliferation of threats.

What Is Network Auditing?

Network auditing refers to the collective measures involved in gathering, analyzing, and studying data on a network, to determine its health in relation to regulatory compliance standards. Network auditing gives businesses insight into how effective their network control and management practices are, especially internal and external network compliance policies and regulations.

Network Auditing Components

Network auditing is conducted through a systematic process, which involves analyzing the following network components:

  • Control Implementation
  • Management
  • Availability
  • Security
  • Performance

Network Audit Steps

A network audit entails gathering data, identifying threats and vulnerability, and compiling a formal audit report, which is then sent on to network administrators. Audits are usually performed by an information system auditor, a network analyst, or another individual with a background in network management and IT security. Both manual and automated techniques are used to gather data and review overall network health.

Here are common network audit steps required to perform a comprehensive network audit:

  1. Record audit details
  2. Ensure procedures are documented
  3. Review the procedure management system
  4. Assess training logs and operations
  5. Review security patches for network software
  6. Review the penetration testing policy and process
  7. Test software
  8. Identify firewall holes
  9. Ensure sensitive data is stored separately
  10. Encrypt company laptop hard disks
  11. Confirm wireless networks are secured
  12. Scan for unauthorized access points
  13. Review the event log monitoring process
  14. Compile a report
  15. Send a report to appropriate stakeholders

It’s worth bearing in mind, although a network audit prioritizes network control and security, it also reviews the operations and measures contributing to network quality of service, network performance, and network availability.

Network Audit Checklist

Conducting a network audit is an essential part of ensuring the functionality and reliability of your business network. If this isn’t made a priority, your network is likely to underperform. The following network audit checklist guides you through the key considerations of an audit. When creating a network audit template, it’s important you include these processes.

✔ Review Your Bring-Your-Own-Device (BYOD) Policy

Your employees will almost certainly bring their personal devices into the workplace and connect them to the network, which causes slower speeds, increases bandwidth demands, and exposes your network to potential security risks. It’s crucial for this practice to be managed carefully, starting with establishing clear and considered policies.

There are challenges associated with developing a robust BYOD policy; these include the use of unapproved third-party applications, exposure to unsecured networks, and the presence of unknown hardware. By reviewing your BYOD policy, you’ll gain insight into which devices are connecting to your network, the vulnerabilities associated with and created by each of them, and who’s responsible for managing the devices. This awareness can help you minimize network exposure as much as possible.

✔ Review Network Cybersecurity Vulnerabilities

Cybersecurity vulnerabilities are weaknesses likely to be exploited by hackers attempting to gain access to your network. These vulnerabilities can exist in many places, including hardware, software, and your physical surroundings. Some vulnerabilities can be resolved with minimal time and effort but identifying and fixing most weaknesses begins with a professional network audit.

Prominent vulnerabilities include outdated security patches, poor password management, and personal devices connecting to your enterprise network.

✔ Review Bandwidth Demands

Bandwidth is’t unlimited, and it must be shared among your users. Bandwidth usage and distribution monitoring can help you determine whether your network needs to be expanded, and whether any individual devices and applications are experiencing bandwidth issues needing to be addressed.

When you have a clear view of bandwidth usage, you’ll gain an understanding of which applications should and shouldn’t be prioritized, and where congestion is happening. Managing traffic flow effectively can even help you improve performance.

To assess bandwidth demand correctly, it’s important you compare wired and wireless connections, as this helps you identify bottlenecks. To gain a complete understanding of which network components you should prioritize, it’s recommended you employ network audit tools.

✔ Review Infrastructure Problems

Your network infrastructure includes both software and hardware components. Hardware includes access points, switches, and cables. Software includes applications, operating systems, and firewalls. Infrastructure doesn’t, however, usually include endpoints like servers and personal devices.

It’s key you examine bandwidth patterns and update patches, as this contributes to the maintenance of a healthy infrastructure. Keep in mind, there are several other notable and common infrastructure problems, like forgotten firewalls and load balancers. Issues of this nature can result in major disruptions within your IT department. A network map can help you diagnose and rectify these issues quickly and efficiently.

✔ Plan Network Upgrades

The most important part of a network audit is what you learn from it. Having a network audit checklist and network audit template is useless unless you rectify any issues. Businesses shouldn’t consider their work done once the network audit report has been compiled. This is the time to determine whether hardware and network upgrades might boost performance.

A network upgrade could involve updating cabling, creating clearer policies, adding more access points, or updating your firewall. Remember, one of the most common reasons behind poor network performance is your hardware needs an upgrade. When a network upgrade is planned and implemented carefully, it can assist your company with resolving connectivity issues and improving the overall user experience.

Best Network Audit Software

In a business environment, dependable network performance is a crucial factor in streamlining operations and maintaining productivity. This can only be achieved when you’re afforded access to clear and complete data regarding your network capacity.
