Confidentiality in InfoSec ensures that a company’s confidential information is only accessible to those individuals with proper access. Keeping confidential information secure also protects companies’ proprietary trade secrets.
There are many ways to breach confidentiality. For instance, an individual may steal a password or share passwords with another person. This may lead to stolen finances, identity theft, or the disclosure of private medical information.
In order to prevent confidential information from being breached, a company must maintain security in its systems. It can include encryption methods, access control lists, and proper equipment disposal. Aside from these methods, a company must also ensure that unauthorized parties are prevented from accessing the assets.
The CIA triad, which is a set of three basic principles: confidentiality, integrity, and accessibility, is a foundation for all security programs. It helps institutions develop security policies and enables them to set up controls.
Basically, non-repudiation in InfoSec means a guarantee of authenticity of an electronic message. It also means that a sender or receiver cannot deny the authenticity of a message. Non-repudiation can be achieved through cryptography. For instance, a sender can encrypt a message using the recipient’s public key.
Another way to ensure the authenticity of an electronic message is to secure envelopes using a shared secret key between parties. This will generate non-repudiation evidence, the best of which is likely to be the cryptographically strong password or passphrase that the receiver must know.
Asymmetric cryptography is an alternative to symmetric encryption. Asymmetric cryptography involves the use of a shared secret key between two parties, one of whom is the sender and the other of whom is the recipient. This can prove to be more secure than a symmetric key exchange.
Asymmetric cryptography also allows for stronger data integrity and has several other benefits. By making use of the latest and greatest in cryptography and other technologies, you can assure yourself of a secure network and a secure message. You can also validate the authenticity of an electronic message using digital signatures and certificates.
Whether you’re dealing with a data breach, computer attack, cybercrime or other threat, an incident response plan can help you minimize the damage and recover from the incident quickly. It’s also an important tool in ensuring a strong security posture for your organization.
An incident response plan will include a variety of steps, including a timeline, prevention, mitigation and recovery. These steps should be tailored to your specific business needs. They should include the right people, tools and physical resources needed to get the job done.
An incident response plan should also include lessons learned. A lesson learned report from a company like Tentacle will help you improve your incident response efforts in the future. It may be used for benchmarking comparisons, training new CIRT members, or to improve your company’s incident response strategy.
An incident response plan should include a disaster recovery plan, which aims to ensure that your organization can handle catastrophic events. Recovery includes bringing systems back online carefully. It also includes modifying procedures and repairing systems that have been compromised. It should also include a recovery time objective.
An incident response plan should also outline the tools that will help you recover your data. These include employee training, documenting your breach, and changes to your security systems. It should also include an after-action meeting. It is important to document the incident, and ensure that the evidence is forensically sound.
Whether you are starting a career in InfoSec or are already an experienced professional, certifications can help advance your career. In addition, certifications demonstrate that you have advanced knowledge in various security disciplines.
CISM, for example, is one of the most widely recognized and respected certifications in the InfoSec field. CISM is based on the ANSI standard 17024, which sets the bar for professional training. It is accepted by a number of Government agencies, commercial employers and organizations, and provides a valuable foundation for assessing information systems.
The CISM certification process uses a 200-800 scoring system, which allows for performance comparisons among candidates. Candidates must also participate in Continuing Professional Education (CPE) to maintain their certification.
For a more general security generalist certification, the Certified Information Systems Security Professional (https://www.businessnewsdaily.com/10743-how-to-become-cissp.html) is a good choice. This certification is widely recognized and is sought after by employers. This certification is not as technical as other security certifications, but it does build a strong foundation of knowledge.
A certificate in penetration testing is a solid entry-level option for professionals who wish to gain experience in security testing. To obtain the CEH credential, you must complete an official training program and have two years of work experience in InfoSec.
