For connecting to a remote machine running over a SSH server we use SSH to access our applications and data. Some primary advantages of using SSH are as follows: 1. We can authenticate the remote machine by using SSH which cannot be possible by telnet and rlogin. 2. We can use encryption method for securing the passwords by using SSH.
The proxy server effectively hides the true network addresses. In practice, many firewalls use two or more of these techniques in concert. A firewall is considered a first line of defense in file and network security. For greater security, data should be encrypted. (www.webopedia.com) Symmetric and asymmetric encryption Symmetric encryption is a type of encryption where the same key is used to encrypt and decrypt the message.
A. RSA RSA stands for Ron Rivest, Adi Shamir and Leonard Adleman. It is a public key Cryptosystem used for secure data transmission. In this, two different keys are used. One is public key used for encryption and other is private key used for decryption. In , they mainly focused on the data security issues in the cloud like: 1) Privacy and Confidentiality which means that once the user hosted the data in the cloud, there should be some guarantee that access to that hosted data will only be limited to the authorized access.
ZoneAlarm Pro 3.0 not only provides cookie control, pop-up ad control but also provides email protection and it can suspend 46 different file types. Unlike other personal firewalls, ZoneAlarm Pro includes Program Control to protect against known and unknown threats. With ZoneAlarm Pro, you can control the ability to specify which programs are trusted to access the Internet, by monitoring all outbound traffic. You can also block and make your computer invisible on the internet-“if you can’t be seen, you can’t be hacked” (Zone Labs).

I read papers and had a solid understanding of OVERVIEW OF FIREWALLS A Firewall is basically a security function which prevents our systems from attacks. That is it acts as wall between our system and remote attackers and makes it difficult for attackers to attack. It is set of related programs which is located at network gateway server which protects private networks from any other network users. . It is set of rules that determine whether packets are safe or not.

It is a form of authentication and encryption. A key is generated and used for encryption and a certificate is generated and used to verify authentication. Symmetric key encryption or secret key cryptography uses a key that only the sender and receiver know. Both the sender and receiver use the same code or encryption to encrypt and decipher the messages.

Different Encryption algorithm are used such as 3-DES (triple-DES), IDEA, Blowfish. For integrity of data and to ensure that data that has arrived is same as data sent, SSH uses keyed hash algorithms based on MD5 and SHA-1 . For SSH, authentication of both sender and receiver is necessary. For client and server authentication, SSH uses stronger and advanced mechanisms such as rlogin style authentication, secret key one-time passwords, per-user public key signatures.  Authorization is ensured in SSH by restricting certain functionalities at server level or account level.
Information throughout the internet can be traveled in a readable format (securityinabox). An important factor of keeping an email secure is encryption. For example, email encryption generates two different types of coding, encryption, which is public, and decryption, which is private to each user. Encryptions are the vaults that safeguard a person’s privacy. Encryptions can turn emails that can be deciphered with a key, and then sends it to anyone else if they have the same key (Klosowski, 2013).
The main focus for this paper will be on how data encryption can help safeguard information being stored in the cloud. Data encryption is a key component in security for cloud computing and is often used when secure information is being transmitted. Keywords: cloud, security, data encryption Using Data Encryption for Security in Cloud Computing Today, businesses and individuals want the ability to access their data anytime and anywhere. As technology advances and the newest devices such as smartphones, tablets, and laptops are released, this ability has increased. The introduction of cloud computing provides the ability for individuals to be able to access their information from various locations and at various times.
