Cybersecurity Awareness
- 1. CYBERSECURITY AWARENESS BY: JOSHUA WISNIEWSKI
- 2. WHAT IS CYBERSECURITY? • It is the practice of shielding any networks, systems, servers, etc. from any form of attack • This includes threats such as phishing, ransomware, DDoS attacks, etc. • This field is important because without it could cause devastating damage to our data and infrastructure
- 3. TYPES OF THREATS There are many different types of digital attacks. They include: Ransomware Phishing DDoS Social Engineering
- 4. RANSOMWARE • It is a form of malware that encrypts the victim’s files on their system • This means you cannot access or modify them • In order to get files back, you must pay the attacker • Otherwise you would risk losing access to your files forever • Companies and organizations are most at risk • However anyone can be a target for ransomware
- 5. PHISHING • It is when a target or targets get coerced into giving personal information • Some of this personal information includes social security numbers, passwords, etc. • This can be done over the phone, by email, text message, or social media • This information can be used by the attacker to commit identity theft or other crimes such as stealing funds
- 6. DDOS ATTACKS • DDoS is an acronym for Distributed Denial of Service • It is a malicious attempt to disrupt normal traffic of a server that is targeted • This could result in servers being clogged with traffic • It would slow down speeds or “crash” the server(s) altogether • This is a costly form of attack, that could cost a company/organization millions (if not billions) of dollars if not resolved quickly
- 7. DDOS ATTACK FROM A HIGH-LEVEL VIEW Just think of server traffic like highway traffic like the picture shown above. If there is DDoS attack, the flow of traffic gets greatly reduced or stopped altogether, causing a traffic jam. Source: Cloudfare
- 8. SOCIAL ENGINEERING • This is when an attacker manipulates a target or targets into giving up their personal information • Some of this information includes banking information, social security numbers, and passwords • They can even convince a target to install malicious software on their device • These attackers can pose as someone they are not to ensure they are trusted • They can pose as a boss/coworker, a gov’t official, a charity representative, etc.
- 9. WAYS YOU CAN PROTECT AGAINST THESE THREATS • Use a strong password with a combination of uppercase and lowercase letters, numbers, and characters • Do NOT use the same password for all your accounts • Use two-step verification for accounts that support them for a better measure of security • Always double-check your emails and look for close details (e.g. grammar and spelling) to make sure it is legitimate • With a shady call on the phone, ask for their supervisor or their employee ID number to make sure it is legitimate (if they hang up or refuse that means it is likely a scam) • Install antivirus software on your computer to help protect you against viruses and malware • Always try and go to reputable websites
