Network Security From IT Industry's Jobs

1 comments
Lacking creativity but loaded with technical intelligence? Network security is a great career to try out in the IT industry.
This field involves securing the information uploaded by various institutions online using authentication processes, firewalls and encryption so that the attacks of potential viruses and hackers can be curtailed. Network security is gaining prominence as greater reliance is placed on the internet. In all spheres of life there is always some level of computer dependency and with the rise of harmful viruses and spiteful hackers, it is necessary to maintain utmost security.

Reality 101

This field demands a great deal of technological insight as network police have to keep themselves updated with all the latest forms of viruses so that they can formulate accurate and effective defense mechanisms. As a network security analyst, you will be expected to create the entire defensive framework of various websites and online data bases using all your computing knowledge.

The first step in network security is authentication and this is achieved in two main levels:

  • One Factor Authentication - This involves the use of a username and password to distinguish between visitors and protect the site from unauthorized users. This is a popular form of authentication which you must undoubtedly be familiar with.
  • Two Factor Authentication - For this you require a security token like an ATM card or a mobile phone to further support your entry. Network security analysts are thus expected to provide the framework that allows this process to further strengthen the security of the site.
Security analysts must also make use of firewalls which ensure that each user is able to see only the data he is authorized to see. This provides additional security to the information on the site. However, firewalls do not give adequate protection against worms or Trojan viruses and so anti-virus software is needed to protect against attacks. Security analysts will also be expected to create anomaly-based intrusion detection systems which will be able to notify the administrator in the event of suspicious behavior to further protect the information. Encryption must also be used to ensure conversations between users remain private and to avoid information loss.

Essentially, a good network security analyst makes use of a wide variety of security measures to protect data. However, this is not a one-time job; security analysts have to constantly monitor the security of their sites and take immediate action whenever the security is compromised. By analyzing previous attacks, they can formulate advanced security frameworks that can effectively deal with future attacks.

This is definitely a crucial occupation within the IT industry that facilitates the basic success of all other sectors. Without a security analyst, private information could be leaked or stolen and the internet would no longer be the useful platform that it is. That being said, there are difficulties as the blame for a compromised web site ultimately falls on the head of the security analyst who has created the defense framework.

As a career, network security is perfect for individuals who are extremely familiar with protocols like transmission control protocol, and internet protocol (TCP/IP). TCP and IP are the basic means for communication between computers and thus to create a security system, one must appreciate them. By fully understanding these protocols one will be able to detect any irregularities on sites and thus fix them efficiently.
Thus there is a heavy workload upon a network security analyst but it is definitely a rewarding career that will expand your technological skills.

The Inside Scoop

Here is a look at the concepts a future network security analyst must know:

  • Understanding of Basic Protocols - As mentioned before, protocols are the foundation of relations in the online world and hence to be a good network security analyst you will have to be extremely comfortable in understanding these protocols.
  • Understanding of Intrusion Detection Systems (IDS) - IDS are present in all secure websites and so a good security analyst will have experience in checking the packets logged in by the IDS to monitor site activity and avoid hackers and viruses. More often than not the IDS will log false attacks but you will never know if they really are false unless you check them. For this you need to be well-versed in the understanding of IDS.
  • Firewalls and Routers - Firewalls ensure that data is not easily available to everyone and routers manage traffic. The two are extremely important for the successful working of any website and so a security analyst must be able to use them efficiently to provide the highest degree of protection. This involves a great deal of practical application as the settings have to be tweaked to suit the particular site. Setting up routers is a somewhat confusing process but as a security analyst you will be expected to be able to do this with ease.
  • Reading of Code and Programming - By being knowledgeable in programming and in reading code you will be able to analyze intrusion attempts better.
  • Ethical Hacking - A security analyst can also use hacking skills to identify weak areas in a site and thus tweak the security framework. This process is extremely effective as it allows you to detect weaknesses before they are found and misused by spiteful hackers.

Besides the knowledge of these concepts, you should also have the following attributes:

  • Patience - Network security demands continuous attention and you will have to check through numerous security reports as well as monitor the daily functioning of the site under your authority and this demands a great deal of patience.
  • Adaptability - The sites you work on will all have different security demands. For instance, a government site will need extremely strong protection while a site advertising a product will need a bare minimum. You should be familiar with all levels of network security.
  • Quick Thinking - You need to be able to solve problems as fast as possible as delays can lead to detrimental losses of important information which must be avoided at all costs. Any threat to the system must be instantaneously detected and deflected.
