1.Protection of the memory keys

The typical threat model in an organization recites in either hardware or software. Attackers are often assumed to have physical access to the sensitive information in various ways. The target for these attackers is mainly to get the encryption key which is hidden in the chip boundary. This increases the workload of the attacker since it requires expertise knowledge. The cryptographic keys unlike most data in the computer memory, are random. Looking through memory structures can be an easy way to reveal the key material. Well made libraries for use like the Local Encryption Services help to a great extent in protecting keys in memory. Key-encryption keys are used to encrypt the key while it is in the memory and then this encrypted key is divided into several parts and then spread throughout the memory spread. Memory holding the key should be immediately cleared as soon as this cryptographic process is finished. To increase the security Master key must be backed up separately.

2.Denial of service (DOS)

It is not possible to completely eradicate DOS but to some extent we can avoid  it. It becomes very difficult to differentiate between a genuine request and a fake  request because both use the same ports and protocols which may resemble each other. Some of the ways to prevent this can be :

·         Purchase a lot of bandwidth: This is the most easiest but the most expensive. Enterprise with a lot of bandwidth would be less susceptible to DOS because it has more bandwidth than an attacker has to clog.

·         Prepare a DOS response: The use of throttling and rate-limiting technologies reduces the risk of DOS attacks. This response stops all the new inbound connections in the event of DOS attacks, allowing only the established connections and new outbound connections to continue.

·         Using DOS attack identification and detection technique: This can help to differentiate between legitimate and malicious traffic. Activity profiling can be used for this, it measures average traffic rates and flag significant increase in traffic. Identifying the DOS attack can help organization to determine the type of attack i.e. DDOS attack or domain name system amplification attack.  

 

3.Preventing Data in cloud

Using the cloud can come with a great ease and a great threat to the data. But if done smartly this can help to a great extent.

·         Use private clouds: Private clouds are more expensive but  much  more secure than public clouds.Private cloud  providers are in better position to monitor your account, enabling them to preemptively deflect attacks and minimize their  impact.

·         Choose passwords wisely: Passwords must be strategically chosen since they are the most avoidable and common cyber security attack. The idle password must be at least 8 character long, utilizes a wide range of symbols, no complete words, no word related with the company. If CEOs credentials get into the hands of cybercriminals, they can  send emails to the employees to take action without the knowledge of the CEO.

·         Use secure data transfer channel: Always encrypt the sensitive data before sending .This reduces the attacks up to a great extent.
