Table of contents
Network Security Engineers help design safer computer networks and identify issues in existing computer systems. They are cybersecurity experts who specialize in protecting against security breaches and incidents.
Working as a Network Security Engineer often comes with a wide range of job duties and responsibilities. They may need to monitor networks to detect security vulnerabilities, test and configure hardware and software, and work with other IT professionals to solve problems.
The job may occasionally involve long hours and stressful situations, but also offers flexibility and stability. Here is a closer look.
What they do
Network Security Engineers are responsible for designing and improving security systems. They protect networks from cyber threats, including malware, bugs, and hacks.
Engineer New Network Systems with Increased Security
Network Security Engineers design (engineer) the network systems used by organizations. They select the hardware and software needed to maintain efficient communication between devices while protecting against cyber threats.
Designing a network requires Network Security Engineers to consider the communication needs of the organization, such as the number of users, the amount of data, and points of vulnerability.
Perform Penetration Testing and Assessments
Network Security Engineers spend most of their work hours running penetration tests and assessing the security and performance of computer networks. They assess networks to ensure that their designs provide optimal security. If they detect any vulnerabilities, they may update the systems and run additional tests.
Penetration testing is also occasionally carried out by dedicated Penetration Testers. However, the Network Security Engineer may oversee the penetration tests. These tests identify vulnerabilities using the same malicious techniques employed by hackers. The test may be automated or require the Network Security Engineer to attempt to breach the network using known hacking methods.
Troubleshoot and Resolve Security Incidents
Network Security Engineers may assist with the troubleshooting and resolution of security incidents. Security breaches are often addressed by other IT staff, including Network Administrators. However, the Network Security Engineer may be brought in to deal with serious breaches or incidents that are not easily resolved.
When troubleshooting an issue, the Network Security Engineer first determines which networks are affected by the problem. They may shut down affected systems to isolate them from the rest of the network, depending on the severity of the threat.
Audit Network Security Solutions Before Implementation
Network Security Engineers help select new security solutions when vendors and suppliers release new products or update existing products. Selecting new security solutions requires the Network Security Engineers to audit the software or hardware to ensure that it meets the needs of the organization.
When auditing solutions from vendors and suppliers, Network Security Engineers analyze its security features and ease of implementation. They need to justify the change by ensuring that the new solution delivers improved security.
Establish Monitoring Protocols for Detecting Security Breaches
Network Security Engineers develop the procedures for monitoring networks. They also develop alerts for notifying the IT department of potential security issues. This may include the creation of automated scripts that actively monitor networks for specific triggers.
Collaborate with IT Staff to Implement New IT Resources
After designing a new network or planning the update to an existing network, the Network Security Engineer collaborates with the rest of the IT staff to prepare for the implementation process. They may need to discuss the project with senior members of the IT department or receive approval from executives before deploying new software or installing new hardware, as these projects may disrupt normal business procedures.
What is the job like
As a security engineer, you must have a near-paranoid eye for little details and errors in your code. These errors become security vulnerabilities,’ as evidenced by recent cases such as the iOS issue and Heartbleed. Bugs are incredibly costly in the security industry; not only do they consume resources and time, but they also damage your users/customers financially and emotionally.
That’s not something you’d want on your conscience! As a result, achieving 99% unit test coverage for your products becomes a need rather than a lofty objective.
You’re constantly trying to learn new things! You must be both a generalist and a specialist at the same time. To safeguard a system, you must understand it completely. Multiply that by the variety of exploits and languages – SQL injections (databases), XSS (javascript), Teardrop (TCP/IP protocols), DDoS (network routing), and Heartbleed (heartbleed) (SSL). You’ve got an ocean in front of you, so jump in!
Glamor specializes in packet analysis, CPU cycles, and process memory dumps. We need to do this a lot on a regular basis – not just type passwords on the screen at random! In fact, it makes you wince whenever a film depicts hacking as simply typing login and password into a black terminal with green font.
On a daily basis, spies, stalkers, and psychologists are required. Days of inactivity can be followed by a burst of interesting activities.
