Important Network Security Skills

Network security tools can keep a company’s internal systems safe, but you also need to comprehend the primary concepts behind networking and cybersecurity. This big-picture understanding can help you know where and when to deploy your tools. You should keep in mind that security applications, as effective as they may be, are merely components of your overall strategy.

Cybersecurity strategies involve multiple components. You use different tools and techniques to

• Identify threats;
• Block intruders from accessing the network;
• Backup and protect data;
• Respond to any intruders who can beat your defenses.

You need a deep understanding of how to accomplish each of these tasks so that you can respond to problems immediately when they arise.

Here is an example of a cybersecurity concept being used in a real-world situation: 82% of cyber-attacks are due to human error, such as weak or stolen passwords. If you believe employees have compromised login details, you cannot simply shut down the whole network. In addition to mandating password changes, you can set up two-factor authentication (2FA). This will require users to get a second code via text, email, or external device when logging in. Even if hackers steal a password, they will not be able to get into the network without the second code.

In this example, you identified the threat and found a solution that still allows employees to access the network with one simple additional step.

An understanding of all networking and cybersecurity concepts can help you come up with similar solutions when issues arise.

Many of a network security pro's duties focus on stopping breaches before they start. However, new demands, such as connections for remote workers, and new hacking strategies can increase the chance of a hack. Network security professionals need to prepare for the worst-case scenario, keeping in mind that their employer needs the network to remain productive.

Preparations for a breach can include constantly backing up data so that it remains saved and accessible in the event of a ransomware attack. Not only will this limit the damage of a hack, but it will also help the company continue operations instead of having to shut down until the data is retrieved.

You might consider compartmentalizing your network so that you can block off compromised sections without shutting the whole system down. You can also back up security system configurations so that you can limit any interruptions by getting right back online with a fully functioning security system.

Contrary to stereotypes, IT specialists do not spend their whole day alone on a computer. Network security pros have to be skilled communicators. They must be able to collaborate with other technical staff members to solve issues and complete tasks. Security problems are time-sensitive and often require quick, coordinated action, so organization and communication between IT experts are essential components of any cybersecurity operation.

At the same time, network specialists are responsible for communicating their needs and plans with company decision-makers, who typically do not have the same level of technical knowledge. These reports require simplifying things without “dumbing them down.”

Finally, many network security experts have to train employees to use the network and embrace good cybersecurity practices. This process requires clearly communicating steps for logging in, dealing with downloads from emails and third-party sites, and using VPNs when connecting remotely. Again, it's essential to communicate this information in a non-technical way that won’t confuse employees.

Software development is not a part of the daily routine for most network security professionals. However, the job often requires knowledge of computer code. Many network security tools require configuration or customization to work on a company’s existing network. Some firms build their tools from scratch, and if you work for a third-party cybersecurity provider, such development projects will be quite common.

An example of this type of software development would be firewalls, which you build or customize using C or Python coding languages. You may also need C++, which is a common language for computer systems, and SQL, which is an important code for database backups and security.

You should also understand the process for building, debugging, and testing your applications.

The field of cybersecurity evolves fast. Several factors drive these rapid changes. Firstly, cybercriminals are constantly coming up with new methods to exploit vulnerabilities. For example, there was a significant increase in ransomware attacks in 2022. Hackers use malware to access databases and encrypt the data, not decrypting it until the owners pay a ransom. You can be proactive by backing up data so that this type of attack does not stop operations.

Secondly, companies have changing needs. Remote and hybrid work arrangements require secure access from outside an office. You can use VPN or proxy servers to secure these remote connections or build a secure app that employees can use to access the network via their smartphone. These steps can strengthen vulnerabilities that hackers might seek to exploit.

Finally, network security professionals need to keep up with the latest cyberthreats. This allows them time to proactively address new hacking methods early before they become an issue.
