Ensuring Network Security in Cloud

Cloud computing has brought about a tremendous change in ways technology used to work and has eased the access of data. Companies, which have yet not shifted to cloud computing, are now thinking about shifting to it. The main reason is the unlimited storage of data that no longer is beyond reach. The main benefit is the saving on cost and maintenance of a data center that no longer needs to be established.

Cloud computing, as its name suggests, can really work as a cloud of information whenever you need it, there and then. However, there is only one issue regarding the use of this technology for which every enterprise is worried about i.e. its security. Just as you need security for every valuable thing, the data also needs to be secured from any intrusion.

Once a cloud technology is integrated, all your valuable data goes out of your hand and someone else takes care of it. You can never be completely sure about how it is guarded. This makes a company vulnerable and therefore, is the only hindrance in adopting this technology so far.

Nevertheless, organizations are opting for it due to the fact that it offers such a tremendous amount of space for data that not only gives access anywhere but stores unlimited data. The only thing that needs to be considered when opting for it is to ensure that there is a considerable amount of security provided to the system so that the data does not fall in the wrong hands.

The risk of data theft or leak is present in various forms. The data is vulnerable to theft in ways such as, an access of information through insecure mobile phone. Another common example is the use of web application that can be downloaded on the network by one of your contractors who is working, or the sharing of password by your database administrator. These and other little backdoors pave the way for breaching of data that can be guarded by an efficient use of securities that have proven to be effective.

To ensure confidentiality and security of the data the first and foremost thing that comes into the mind is firewall. However, that alone is not going to ensure security. There are numerous ways, which can be used to keep your data saved. Here are a few techniques that should be incorporated when adopting this technology that can help you run your cloud without any worries.

  1. 1.      Access monitoring

Monitoring who accesses which information is the MOST important rule when it comes to cloud security. A record of what has been accessed, from where and by whom is the key of keeping track for security.

  1. 2.      Limiting Access

Not all data should be available to be accessed by everyone on the network who has been given the ID and password. The system should ask if the person has been assigned or have gained the rights for certain information.

  1. 3.      Classification of Data

You have established a cloud and you have uploaded all the valuable information over it. Now it needs to be sorted out and placed in order, just so that it can be found and used by specific individuals. Classify which information is more sensitive and which is less sensitive. Now the information, which is less sensitive, could be accessed with ease.

  1. 4.      Heavy encryption

Just as access to valuable things is complex and difficult, to ensure their security, data should be secured the same way, too. Encrypt the more important and confidential data to ensure its safety. That is to say that the data you classified as sensitive should be kept in heavy encryption that makes access to it a complex process so that only the specific people could get access to it.

  1. 5.      Limiting Access In Context With Location

The access to information should be limited outside an organization. For example, if an employee is trying to access the information outside an organization, he should therefore go through certain validation processes to prevent data theft or leak.

In addition, there should be no access to the most sensitive information outside an organization from devices such as mobiles.

  1. 6.      Scrutiny Of Users

Users such as your data administrators and others who could access the sensitive information should go through scrutiny to ensure the security of data being handled. Sometimes, a training might help in keeping the information secure.
