What are the 4 types of IT security?

Every organization has some data to protect. The data, if stolen can cause huge damage to an organization both reputational and financial. Hence, it becomes vital to secure all the paths via which one can access data.
Here is when IT Security comes in play. It is nothing but deploying strategies that can guarantee end to end security to protect the Confidentiality, Integrity and Availability of data whether it is in transit or at rest.

1.Application Security:
With almost entire population being dependent on one or the other kind of application to get their job done, it has really become important to tighten the security around them. Applications can be of any kind such as Websites, Mobile apps, Cloud hosted apps so on and so forth.
It is always better to introduce security way early into the development of application rather than doing it later. It is also important to do the timely evaluation of your application against vulnerabilities.

2.Network Security:
Once the attacker is in your network, there is no way to stop him from doing the damage. Hence, network security both internal and external becomes crucial to the well-being of an organization. It makes sure to restrict access to only those who are supposed to be accessing the network.
A detail vulnerability scan of your network can help analyze the loose points one can exploit.

3.Cloud Security:
Cloud came as a blessing to many organizations who were investing in a great deal of resources just to maintain servers. It helped a lot organizations strengthen their Business Continuity Plans. With organizations moving their entire data to the cloud, it has become a favorite target of attackers.
It is vital to configure cloud securely and in the best interest of the business. There have been recent cases where in AWS S3 buckets were leaked and lot of data was gone due to making them accessible to public. A cloud access security broker can be used to tighten the cloud security.

4.Internet Security:
It involves protecting the data that is coming in and going out of your device, browser etc. It makes sure that the data is not altered or spoofed and thus maintains the integrity. This can be achieved by encrypting the data in transit out of many solutions. Firewalls can be used and deployed on the device to filter out the traffic that could pose a harm to the security of the data.
