Security Threats
Security involves protecting information by preventing and detecting unauthorized access. It aims to ensure confidentiality, integrity, and privacy of data through prevention, detection, and reaction measures. Common threats include viruses, worms, Trojan horses, eavesdropping, password cracking, denial-of-service attacks, and network spoofing. Effective security requires understanding how information could be compromised through various means such as loss of confidentiality, integrity, or availability.
Cyber Crime & Security
Computer crime, or Cybercrime, refers to any crime that involves a computer and a network, where the computers may or may not have played an instrumental part in the commission of a crime.
The term computer system security means the collective processes and mechanisms by which sensitive and valuable information and services are protected from publication, tampering or collapse by unauthorized activities or untrustworthy individuals and unplanned events respectively.
Hacking
The document discusses different types of hackers, including white-hat and black-hat hackers. White-hat hackers enjoy learning computer systems, while black-hat hackers, also called crackers, engage in illegal activities like stealing credit cards or passwords. The document also outlines common hacking methods like port scanning and denial of service attacks. It recommends steps for client-side security including anti-virus software, personal firewalls, and encryption to protect against hacking threats.
Attacks Types
A denial-of-service (DoS) attack overwhelms a system's resources to prevent it from responding to requests, while a distributed denial-of-service (DDoS) attack uses multiple compromised systems. Common DoS/DDoS attacks include TCP SYN floods, teardrops, smurfing, and ping of death. In 2018, GitHub experienced a record 1.35 terabit DDoS attack. SQL injection occurs when malicious SQL queries are passed through user inputs to access databases. Man-in-the-middle attacks involve an attacker intercepting communications between two parties. Phishing scams use fraudulent emails to steal user information. Password attacks aim to obtain passwords through brute force guessing or

It emphasizes that media misconstrues hackers as criminals, and explains that real hackers have strong ethics and help catch cyber criminals, unlike crackers who hack systems illegally. The rest of the document provides an overview of skills, subjects, and basic concepts needed for ethical hacking.
Network Threats
Most users do not see front-line activity and 'normal business usage' to be a contributing factor to network security; but it's not all about the back-end. Business behavior is a direct impact to business information system risks.
Hacking
Hacking, cracking, and hacktivism have a complex history. Early hackers believed that information should be free and decentralized. Over time, laws like the Computer Fraud and Abuse Act were passed to criminalize unauthorized computer access. Now, some hackers conduct ethical hacking and penetration testing to improve security. However, crackers aim to damage systems, while hacktivists hack for political reasons. Debates continue around definitions and the ethical implications of different forms of hacking activity.
Computer Forensics
Computer forensics is used to discover evidence of computer crimes by collecting, preserving, and analyzing digital evidence from computers and storage media. It helps criminal and civil legal cases involving issues like espionage, intellectual property theft, employee misuse of computers, and medical billing fraud. The computer forensics process includes securing evidence, making copies or images of storage devices, examining files and locations where deleted or hidden data may be stored, and documenting the investigation. Maintaining control of intellectual property and trade secrets is challenging as organizations increasingly process data overseas where there is greater risk of information leakage.

NewIinternet security
Internet security involves protecting systems and data from unauthorized access. Common security threats include hacking, viruses, phishing, and denial of service attacks. It is important for users to implement security measures like firewalls and keep software updated to prevent intrusions and thefts of personal information.
Ransomware 101
Ransomware is a type of malware that encrypts files and denies access to systems until a ransom is paid. It works by infecting systems through phishing emails or other hacking methods and then encrypting files. The criminal then demands payment, often in Bitcoin, in exchange for decrypting the files. Organizations can help prevent ransomware by regularly backing up data, segmenting networks, using antivirus software, training employees on security best practices, and carefully monitoring and scanning all email attachments for threats.
