What is Encryption? | Data at Rest, in Transit | Key Management | the Importance of Information Security Policies
66. What is encryption and why are information security policies important, and do you offer comprehensive I.T. security documentation?
Encryption has become an extremely important element of information security, due in large part to ensuring the safety and security of sensitive and confidential information. With advances in computing and technology, more and more transactional activities are being conducted electronically, ultimately requiring a need for ensuring the confidentiality and integrity of data traversing networks. Simply stated, encryption is the process of transforming readable, plaintext information into an unreadable cipher text for protecting the original data source from disclosure to unauthorized parties. With the ever-growing regulatory compliance laws, legislation, and industry specific mandates, having a well-defined encryption policy is a must, especially HIPAA, GLBA, and PCI DSS requirements, just to name a few notable laws and mandates.
When discussing encryption in the context of information security, it generally revolves around the concepts of data at rest, along with data in use | transmission, and having a well-defined key management policy in place. From protecting online transaction with Transport Layer Security (TLS) | Secure Socket Layer (SSL) security protocols, to incorporating column, file and full disk encryption for data at rest, encryption is being utilized seemingly everywhere, and for good measure.
The Importance of Information Security Policies for a Well-Defined Encryption Program
Data breaches, cyber security threats, and untold numbers of other malicious attacks are forcing organizations to secure sensitive and confidential data, at rest, and while in transit. The challenge for most organizations with encryption is not so much the effectiveness of it - it works very well - but the adoption and continued commitment for ensuring its use, whenever necessary. From online banking transactions, to I.T. engineers establishing secure connections, encryption is a must for organizations, and an excellent place to start is a professionally developed, comprehensive, and well-defined encryption and key management policy and procedure document.
Hundreds of Policies to Choose from, Including Encryption & Key Management Templates
The very best place to start for ensuring encryption practices are being followed is with a professionally developed, high-quality, and extremely well-written encryption policy, such as the one offered by FLANK. Included with the industry leading FLANK21 set of documents are literally hundreds of other operational, business specific, and information security policies, procedures, forms, checklists, templates, provisioning and hardening documents - and much more.
