CYBERSECURITY AWARENESS

CYBERSECURITY AWARENESS DEFINE CYBERSECURITY WHAT IS CYBERSECURITY? • Cybersecurity is a complete approach • Builds a strong barrier against illegal access, exploitation • The goal is to create a robust barrier • Safeguards digital information IMPORTANCE OF CYBERSECURITY WHY IS CYBER SECURITY IMPORTANT IN TODAY’S LINKED WORLD? • Data is becoming more accessible • Cybersecurity measures are crucial. • Cyber attacks have a negative impact • To guarantee integrity WHAT ARE THE KEY CONCEPTS IN CYBERSECURITY? • Cybersecurity fundamentals encompass availability, integrity, and confidentiality of data. • Confidentiality restricts data access to authorized users • Integrity guarantees data accuracy and prevents unauthorized alterations • Availability ensures data is accessible when required TYPES OF CYBER THREATS TYPES OF CYBER THREATS • Phishing • Spear phishing attack • Malware • Ransomware • Trojans horse • Spyware PHISHING AWARENESS (VIDEO 1:34 MINS) SPEAR PHISHING ISN’T JUST EMAIL (VIDEO 1:30 MINS) EXAMPLES OF CYBER ATTACKS EXAMPLES OF CYBER ATTACKS • Data breaches and denial-of-service assaults are examples of cyberattacks. • The goal of these attacks is to interfere with operations and weaken digital systems. • Some examples include,The WannaCry ransomware in 2017 disrupted systems across the world. • In 2017, millions of people’s personal information was stolen by Equifax. CYBER ATTACK EXAMPLE IN TEXAS DALLAS COUNTY • An international cyber hacker group targeted the Dallas County computer system, threatening to publish sensitive information unless a ransom is paid by Friday. • The cyber incident was detected on Oct. 19, with outside cybersecurity experts brought in to contain the threat and prevent file encryption. • While the county’s computer systems remain operational, concerns arise about potentially extracted data during the attack. • Hackers likely infiltrated the system through a phishing email, highlighting the risks of social engineering tactics in cyber attacks. • https://www.youtube.com/watch?v=zb38kIr5eu0 CYBER ATTACK EXAMPLES IN TEXAS – HOUSTON METHODIST HOSPITAL HEALTH SYSTEM • In 2018, Houston Methodist Hospital, a leading healthcare provider in Texas, experienced a ransomware attack that encrypted patient records and disrupted medical services. • The cybercriminals demanded a substantial ransom for the decryption key, impacting patient care and hospital operations. • The incident raised concerns about the vulnerability of healthcare institutions to cyber threats and the importance of robust cybersecurity defenses. • https://www.youtube.com/watch?v=i899TfS-P_M CYBER ATTACK EXAMPLES IN TEXAS – AUSTIN POLICE DEPARTMENT • In 2017, the Austin Police Department in Texas fell victim to a sophisticated cyber attack that compromised confidential case files and sensitive law enforcement data. • The breach, believed to be a targeted hacking incident, exposed operational vulnerabilities within the police department’s digital infrastructure. • The cybercriminals exploited weaknesses in the department’s network security, highlighting the critical need for enhanced cybersecurity measures in law enforcement agencies. • https://www.youtube.com/watch?v=lir36v3H5kU FIREWALLS • firewalls monitor and control network traffic • They filter out unsolicited connections and undesirable traffic • Firewalls stop unwanted users from accessing company networks • Ncessary to preserve the integrity and security of networks ANTIVIRUS SOFTWARE • Set up endpoints and servers using antivirus software • To minimize infection and data loss, identify and eliminate malware • Trojan horses, worms, and viruses are the objectives of antivirus software • Critical for eradicating and halting harmful malware ACCESS CONTROLS • Access controls limit user access based on roles and permissions. • They use login information to manage data and system access. • This minimizes the risk of insider attacks. • Limits access to private data effectively.
