Ways to avoid computer infection
Antivirus software (AVS) is...
Antivirus software (AVS) is a special program designed to detect, prevent, and remove viruses and other malware from a computer
what is social engineering?
Social engineering is a type of cyberattack that uses human psychology and emotions to gain access to information, systems or networks, for example in a company.
What is encryption?
Encryption is the process of converting plain text or data into a coded from to prevent unauthorized access.
What is ransomware?
Ransomware is a type of malware that encrypts a victim's files and demands payment in exchange for the decryption key.
protecting computers in our modern world
In today's digital world, protecting computers from malware and cyber-attacks is a critical aspect of information security. The use of anti-virus software (AVS) is one of the main methods of protecting computers, including signature detection, behavioral analysis and cloud protection.
why is social engineering so prevalent today?
Today it is often easier to manipulate people than to hack the system.
The difference between symmetric encryption and asymmetric encryption.
Symmetric encryption
Uses the same key for encryption and decryption
Asymmetric encryption
Uses two keys, a public key and a private key, to encrypt and decrypt data.
Why are Proactive measures and Reactive measures needed?
By implementing these measures, individuals and organizations can reduce the risk of ransomware attacks and minimize the impact of a successful attack.
What are Cyber weapons, Cyber-military attacks?
Cyber-military attacks are malicious acts carried out using information technology to damage computer systems, networks or data, as well as to counter, intelligence or disinformation.
Cyber weapons are advanced tools or software designed to carry out attack in cyberspace.
Name three types of social engineering.
Phishing
Vishing
Smishing
What applications use encryption?
email communication
online banking
e-commerce
secure file transfer protocols
Social engineering in our modern world
Social engineering will evolve as the ways to protect information grow every day. Therefore, it is easier to deceive a person than to try to hack a program.
Ways to avoid computer infection:(4)
Methods of protection against social engineering.
using strong and unique passwords
two-factor authentication
keeping your software and security systems up to date
being careful about emails, phone calls, or text messages that ask you to provide confidential information
why do you need encryption?
it provides security against cyber threats and unauthorized access
it helps protect sensitive data from cybercriminals, hackers, and other malicious actors
without encryption data can be easily intercepted and compromised
What are the reactive measures?
Use antivirus software: Make sure your antivirus software is up to date and running on all devices.
Use firewalls: Firewalls can help block unauthorized access to your network and prevent ransomware attacks.
Limit access to sensitive data: Only authorized employees should have access to sensitive data.
Have a disaster recovery plan: The plan should include steps to isolate infected systems, restore data from backups, and report the incident to law enforcement.
Antivirus software techniques:
What is Phishing, Vishing, Smishing?
Phishing attacks usually involve sending an email that appears to be a legitimate source, such as a bank, to force a person to give confidential information.
Vishing is a type of social engineering attack that involves using voice messages to get people to tell confidential information.
Smishing is a type of social engineering attack that involves using text messages to get people to tell confidential information.
What are the preventive measures?
Use antivirus software: Make sure your antivirus software is up to date and running on all devices.
Use firewalls: Firewalls can help block unauthorized access to your network and prevent ransomware attacks.
Limit access to sensitive data: Only authorized employees should have access to sensitive data.
Have a disaster recovery plan: The plan should include steps to isolate infected systems, restore data from backups, and report the incident to law enforcement.
Cyber weapons techniques:
Malicious Software: Software specifically designed to infiltrate, disrupt or detect instances of systems or networks
Exploits: Code or techniques that exploit vulnerabilities in software, hardware, or network configurations.
Botnets: Networks of hijacked computers or devices that can be controlled remotely for coordinated attacks.
