Basic approaches in information and cyber security.
Analyze how pretty good privacy secures email by providing authentication and confidentiality through hashing, encryption with public and private keys, and backend transparency.
Explore the Data Encryption Standard and how it protects digital data with a 64-bit block, 56-bit key, and 16 rounds of expansion, permutation, and s-box substitutions.
Explore how digital signatures authenticate message origin and integrity using hashing and asymmetric keys (RSA) within digital signature standards, with applications in email security and data protection.
Explore secure electronic transactions using encryption, digital signatures, and digital envelopes to protect confidentiality, data integrity, and authentication among cardholders, merchants, issuers, and payment gateways.
Monitors network traffic for suspicious activity as an intrusion detection system, differentiates activity from false alarms, and blocks intruders via a security information and event management system.
Explore how firewalls control traffic between networks, using hardware or software implementations, packet filtering, and stateful packet inspection, proxy and circuit-level gateways to enforce rules by IPs, ports, and protocols.

You must have heard of the word cyber security, making headlines in the news, internet, social media, IT forums, etc. However, has it ever occurred to you that what is cyber security or why does the security administrator of your organization keep on talking about the importance of cyber security?
Fundamentally, cyber security is the body of technology, process, and practice, designed to protect systems, networks, programs, and data from cyber risks like cyber attacks, damage, or unauthorized access. It is also referred to as information technology security. With cyber attacks evolving today as a danger to organizations, employees and customers, cyber security plays a very crucial role in prevention against such security threats.
As we have entered into this new decade, we can already see new challenges arising in cyber security since day one! It is no surprise to see that cyber security is constantly on a rise and there is a lot in store for the near future. Today, companies have become more technologically reliant than ever and the trend doesn’t seem to stop. Rather, it looks like this technological reliance will keep evolving in the long term.
Almost every organization nowadays, uses cloud storage services like Dropbox or Google Drive to store their confidential data and sensitive information. If not taken proper online security measures, this data present online can easily be exploited by cyber criminals.
