"Cybersecurity Essentials: Basic Information Security Knowledge Everyone Should Know"

IMPORTANCE OF CYBERSECURITY

Because our world is becoming more and more dependent on digital systems and the information they hold, cyber security is becoming more and more vital. This data may be pecuniary (trade secrets or intellectual property) or personal (finance data, medical records, etc.). This information is shielded by cybersecurity against a number of risks, such as:

• Theft: Data can be taken by cybercriminals and sold on the dark web or used for their own purposes.
• Damage: Data corruption or destruction by hackers can cause major disruptions for both individuals and corporations.
• Unauthorized access: Cybercriminals are able to enter computer networks and systems, giving them the ability to conduct further attacks or steal information.

CYBER THREATS

While there are many advantages to the digital age, there is also a rising risk: cyberattacks. These attacks are getting more regular and sophisticated, putting people, companies, and even entire countries at significant risk. Here's a brief synopsis:

• Enhanced Frequency: Particularly since the pandemic, there has been a notable surge in the frequency of cyberattacks. Attacks have doubled, according to the International Monetary Fund (IMF), underscoring the need for cybersecurity precautions.
• Changing Strategies: Assailants are always coming up with fresh ideas. Ransomware can destroy vital infrastructure, phishing scams are becoming more convincing, and social engineering techniques take advantage of people's trust. Furthermore, there is a serious risk to national security from state-sponsored attacks.
• Increasing the Scope: Nobody is secure. Cybercriminals prey on individuals in order to profit financially, while companies experience operational disruptions and data breaches. Because it handles sensitive data, the banking sector is especially vulnerable.
• Greater Impact: Cyberattack-related financial losses are rapidly increasing. Reputational harm and the requirement for security updates can be even more detrimental to businesses than direct costs. Power grids and other critical infrastructure are becoming more and more vulnerable.
• Exploiting Weaknesses: There are additional attack vectors because of how linked our society is. Systems can be compromised via supply chain weaknesses and out-of-date software.

INFORMATION SECURITY VOCABULARY

Penetration testing (also called pen testing) is the practice of testing a computer system, network, or Web application to find vulnerabilities that an attacker could exploit. Phishing – Phishing is a method of trying to gather personal information using deceptive e-mails and websites.

PRINCIPLES

The three main tenets of information security are availability, integrity, and confidentiality (CIA). These three ideas are interpreted as the CIA triad when combined. The secure use, storage, and transfer of information is a fundamental necessity of information security, which is upheld by these three guiding principles. Here's more details about these ideas:

1. CONFIDENTIALITY: The goal of confidentiality is to shield data from unauthorized access and unapproved broadcasting. Here, maintaining the privacy of sensitive information and ensuring that only those with the proper authorization can access it are the main objectives. Confidentiality is preserved by the use of cryptography.
2. INTEGRITY: The goal of data integrity is to preserve the validity, correctness, and consistency of the information. It also aims to constantly protect data from being changed.
3. AVAILABILITY: The simplicity with which authorized users can peruse the material with the least amount of disruption is shown in the third principle. Availability serves the primary function of supplying applications, technology infrastructure, and data to the organization as needed. One type of availability is data kept on the cloud. Here, authorized users can quickly access data from any system-connected device. These three information security principles work together to provide stability and efficacy within an organization.

COMMON CYBER THREATS

1. VIRUS:

   Viruses are a subgroup of malware. A virus is malicious software attached to a document or file that supports macros to execute its code and spread from host to host. Once downloaded, the virus will lie dormant until the file is opened and in use. Viruses are designed to disrupt a system's ability to operate. As a result, viruses can cause significant operational issues and data loss.

2. SPYWARE:

   Spyware is malicious software that runs secretly on a computer and reports back to a remote user. Rather than simply disrupting a device's operations, spyware targets sensitive information and can grant remote access to predators. Spyware is often used to steal financial or personal information. A specific type of spyware is a keylogger, which records your keystrokes to reveal passwords and personal information.

3. TROJAN VIRUS:

   Trojan viruses are disguised as helpful software programs. But once the user downloads it, the Trojan virus can gain access to sensitive data and then modify, block, or delete the data. This can be extremely harmful to the performance of the device. Unlike normal viruses and worms, Trojan viruses are not designed to self-replicate.

4. RANSOMWARE:

   Ransomware is a particularly nasty type of malware that restricts access to your data or device and demands a ransom payment for its return. It's like a digital kidnapper holding your files hostage!

COMMON THREATS

1. Insecure Passwords

   The issue is that weak passwords are simple to figure out or break utilizing automated technologies. Passwords like "password123," birthdates, or pet names are a few examples. The risk is increased when a password is used on many accounts.

   How Attackers Take Advantage of It: To guess weak passwords, hackers employ strategies like dictionary assaults and brute-force attacks, which involve attempting every conceivable combination. Credential stuffing is the practice of attempting to log into other accounts using stolen password lists from data breaches.

2. Antiquated Software

   The issue is that flaws in software are always being found. The most recent security patches for these vulnerabilities might not be installed on outdated software, leaving your machine vulnerable to intrusions.

   How Attackers Take Advantage of It: To obtain unauthorized access to systems, hackers look for hardware with out-of-date software and take advantage of known flaws. They could be able to use this to interrupt operations, steal data, or implant malware.

SAFE INTERNET PRACTICES

Guarding Your Login Credentials:

• Strong Passwords: Create complex, unique passwords for every account. Use a password manager to generate and store them securely. Avoid common passwords and resist the urge to reuse them across different platforms.

Multi-Factor Authentication (MFA)

Whenever possible, enable MFA for an extra layer of security. This usually involves a code from your phone or a fingerprint scan in addition to your password.

Secure Browsing

• HTTPS Everywhere: Look for the padlock symbol and "https://" in the address bar before entering any personal information on a website. "HTTPS" indicates a secure connection that encrypts your data.
• Beware of Phishing: Don't click on suspicious links or attachments in emails, even if they appear to come from legitimate sources. Phishing emails often try to trick you into revealing.

Software Security

• Updates are Crucial: Regularly update your operating system, web browser, and all software applications on your devices. Updates often include security patches that fix vulnerabilities that attackers can exploit.
• Antivirus and Anti-Malware: Use a reputable antivirus and anti-malware program to scan for and block threats. Keep these programs updated as well.

Social Media Intelligence

• Privacy Settings: To manage who can view your information, check and modify your social networking platform privacy settings. Take care of what you disclose in public.
• Online Stranger Danger Is Not Extinct: Reject friend requests and unsolicited texts from strangers. Use caution when disclosing personal information online.

Be Wary of Online Scams

• If it Sounds Too Good...: Be skeptical of offers that seem too good to be true, like get-rich-quick schemes or lottery wins. These are often scams designed to steal your money or personal information.
• Do Your Research: Before investing in anything online, research the company and the offer thoroughly. Read reviews and check with reputable sources.

IMPORTANCE OF ENCRYPTION

Encryption conceals data by scrambling it, so that anyone who tries to view it sees only random information. Encrypted data can only be unscrambled through the process of decryption. Encryption is essential for protecting users' online activities.

IMPORTANCE OF SECURE CONNECTIONS

• Safeguarding Transactions: A secure connection guarantees that the data you exchange with the website is safeguarded when you make purchases online or use your bank account. This is especially crucial for financial transactions involving credit card numbers and other sensitive data.
• Stopping "Man-in-the-Middle" Attacks: These attacks entail hackers interfering with your communication with a website.
• Building Confidence and Trust: Reputable websites are indicated by secure connections that are shown through HTTPS and padlock icons in the address bar of your browser. This gives you peace of mind that your data is being handled safely.
• Mitigating Identity Theft: Secure connections encrypt your data, making it far more difficult for hackers to steal and utilize your personal information fraudulently.

TIPS FOR MOBILE SECURITY

1. HAVE A SECURE LOCK PASSWORD
2. BE MINDFUL OF WHAT YOU DOWNLOAD
3. KEEP YOUR SOFTWARE UP TO DATE
4. DON'T ENTER INTO UNKNOWN LINKS
5. DOWNLOAD MOBILE SECURITY SOFTWARE
