In the event of a breach, it is important to have an incident response plan in place to minimize the impact and prevent further damage.
• What is Phishing ? And How To Protect Yourself Against Phishing.
Phishing is a type of cyber attack in which attackers use phishing emails, websites, or other means to trick individuals into revealing sensitive information, such as usernames, passwords, card numbers, etc. credit or other personal information.
Phishing attacks often come from a trusted source, such as a well-known company or organization, and may contain calls to action that trick recipients into providing sensitive information. For example, a phishing email might claim that the recipient's account has been compromised and they need to click a link to reset their password.
Phishing attacks can take many forms, including:
1. Spear phishing: Spear phishing is a targeted attack that focuses on a specific individual or organization, often using information gathered from social networks or other online sources to launch the attack. become more convincing.
2. Whaling: Whaling is a type of phishing attack that targets people of high status, such as executives or celebrities.
3. Smishing and vishing: Smishing and vishing are phishing attacks respectively that use text messages or voice calls to trick individuals into revealing sensitive information.
How To Protect Yourself From Phishing Attack.
To protect yourself from phishing attacks, it's important to be careful when opening emails or clicking on links from unknown sources. Always verify the origin of an email or message before providing sensitive information, and use two-factor authentication to add an extra layer of security to your account. Additionally, organizations can help protect their employees and networks by implementing email filters and security awareness training programs.
• What is Phishing Techniques ? And how to protect against phishing techniques.
Phishing is a method used by attackers to carry out phishing attacks, designed to trick individuals into revealing sensitive information. Some common phishing techniques include:
1. Phishing emails: Phishing emails are the most common type of phishing attack, where attackers send phishing emails that appear to come from a legitimate source, such as a trusted bank or organization other. These emails often contain a link to a fake website that looks like the real one, but is designed to collect user logins or other sensitive information.
2. Phishing attack: An online phishing attack is a more targeted type of phishing attack in which attackers use information gathered from social media or other sources. to create a more personalized email that appears to be from someone the recipient knows or trusts. These attacks can be more convincing and harder to detect than standard email phishing attacks.
3.Smishing: Smishing is a type of phishing attack that uses SMS messages instead of emails. Attackers send phishing text messages that appear to come from a legitimate source, such as a bank or other trusted organization, with a link to a fake website designed to get information user logins or other sensitive information.
4.Vishing: Vishing is a type of phishing attack that uses voice calls instead of emails or text messages. Attackers impersonate legitimate organizations or individuals and try to trick victims into revealing sensitive information over the phone.
5.Pharming: Pharming is a type of phishing attack in which attackers redirect victims to a fake website even if they enter the correct URL of the website. This is done by exploiting vulnerabilities in Domain Name System (DNS) servers or by installing malware on the victim's computer.

• What is denial of service (DoS) attack? And How To Protect Yourself Against denial of service (DoS) attack.
A denial of service (DoS) attack is a type of cyber attack that disrupts the normal operation of a website, network, or service by overwhelming traffic, data, or requests. In a DoS attack, an attacker floods a targeted system with such excessive amounts of traffic or data that the system is unavailable or unusable to legitimate users.
DoS attacks can be carried out in many ways, including:
1. Network-based attacks: These attacks flood the target system with traffic from multiple sources, overloading network bandwidth and making it inaccessible to legitimate users.
2. Application-based attacks: These attacks target specific applications or services running on the target system, such as a web server or database, by sending requests Malicious requests consume server resources and cause the server to crash.
3. Distributed Denial of Service (DDoS) Attacks: DDoS attacks involving multiple compromised computers or devices, known as botnets, are used to flood target systems. target traffic from multiple sources, making it extremely difficult to identify and mitigate the attack.
The consequences of a successful DoS attack can be severe, ranging from lost revenue and reputational damage to prolonged downtime and lost productivity. To prevent or mitigate DoS attacks, organizations can deploy a variety of security measures, including firewalls, intrusion detection systems, load balancers, and content delivery networks. It is important to regularly monitor network traffic and perform vulnerability assessments to identify and address potential vulnerabilities before an attack occurs.
