Study Notes
Cybersecurity Essentials - Module 3
-
Mobile Applications: Mobile apps are designed for ease of use, but not always security. Common vulnerabilities include weak passwords, malware, and poor design.
-
Mobile Application Security: For enhanced security, use strong passwords (long, mixed characters, letters, numbers, symbols, capitalization), app store applications, and multi-factor authentication (MFA).
-
Rooting and Jailbreaking: Some users modify device restrictions to install non-approved apps (rooting/jailbreaking). This practice enhances functionality but also introduces vulnerabilities. Device manufacturers restrict certain activities and remove apps from stores if security standards aren't met.
-
Desktop Software: Desktop software, whether locally stored or cloud-based, requires security measures. Weak passwords, lack of physical security, and non-HTTPS browsing pose risks. Ensure antivirus software, VPN usage, strong passwords, MFA, physical security, and HTTPS browsing are employed.
-
Business Software: Business software automates transactions, manages data, etc. Cyberattacks, like ransomware, endanger sensitive company data. Protecting data requires employee education and robust security tools for prevention, detection, and response.
-
Corporate Network: To secure files, systems, and resources, limit network access. Internal network sharing should adhere to company-owned hardware guidelines. Enforce company policy on data sharing (need-to-know basis). File sharing should be manageable, not unnecessarily difficult.
-
Corporate Network (continued): Consumer-level cloud and sharing services have security weaknesses. Insecure settings can expose businesses to data breaches.
-
Corporate Network (continued): Security depends on the weakest link. Methods for network sharing include on-premises, cloud-based sharing, and proper use of freeware accounts.
-
Recap (Module 3): Strong passwords, antivirus/malware software, VPNs, and updates are vital for securing apps and devices. Hackers target sensitive data, intellectual property, trade secrets, and financial data. Multifactor authentication is essential for data, information, and consumer trust.
Cybersecurity Essentials - Module 3: Public Browsing
-
Public Browsing Concerns: Public browsing poses significant security risks. Public wifi is often unencrypted, making data easily intercepted. This compromises data and credentials. Public wifi access makes devices vulnerable to attacks.
-
Public Browsing Risks: Session hijacking occurs when an attacker intercepts and hijacks the user’s online session. Shoulder surfing involves attackers in public areas to see essential information.
-
Social Networking: Social networking sites use HTTPS, but users should verify website security before sharing data. Follow site's privacy and security settings to manage risks.
-
Instant Messaging: Instant messaging systems often lack robust security protections, such as encryption or sender authentication.
-
Internet Browsers: Websites using HTTP are less secure, especially on public WiFi, as data travels in plain text. Use HTTPS to encrypt data. Be vigilant to misleading URLs which could be malicious.
-
Recap (Public Browsing): Data can be tracked and sold as public WiFi is unencrypted. Public browsing data can be intercepted by hackers.
Cybersecurity Essentials - Module 3: Browser Management
-
Browser Configuration: Browsers need configuration for a secure browsing experience. Manage plug-ins, extensions, toolbars, and configure security zones.
-
Browsers (Types): Common Browsers such as Chrome, Edge, Firefox, etc. are frequently updated.
-
Security Zones: Security zones in browsers can restrict access to websites and can help protect devices. Modern browsers don't use zones as much.
-
Add-ons: Use appropriate and supported add-ons (plug-ins, extensions, toolbars), as outdated or malicious add-ons can introduce security vulnerabilities.
-
Cookies: Cookies are text files with small pieces of data that aid internet use. Cookies have types, including session cookies, persistent cookies, authentication cookies, tracking cookies, and others.
-
Security Certificates: SSL certificates verify website identity, enabling encrypted connection. Root certificate stores, such as Apple, Microsoft, Mozilla, and Google, maintain trust in websites by using certificates of authority.
-
Browser Updates: Staying updated with browser versions is paramount to protecting devices. Automatic updates are ideal, and prompted updates should be used when available.
-
Recap (Browser Management): Keeping browsers updated, managing add-ons, understanding security certificates and cookie types, and employing safe browsing best practices are crucial for securing devices and data.
Cybersecurity Essentials - Module 3: Additional Topics
-
Browser Cache and History: Browser caches store downloaded webpages for efficient loading. The cache can impact performance. Browser history can be helpful or harmful. Use clear history & cache options, or manage cache space.
-
Private Browsing: "Incognito" mode does not save browsing history, cookies, site data, or form data - but it doesn't hide activity from employers, schools, and ISPs.
-
Malicious Websites: Be aware of misleading URLs, poorly designed sites impersonating genuine ones. Malicious code and phishing scams are common on harmful sites.
-
Safe Websites: Identify safe sites using Whois Lookup, reviews, HTTPS, and trust seals.
-
Adware & Popups: Adware displays unwanted ads, is bundled with apps, collects data, tracks online activity, can alter websites and degrade performance. Security measures are required to mitigate issues.
-
Redirection: Redirection aims to direct users to advertising or dangerous code. Avoid hijacking by using updated browsers and software. The use of malware, unwanted add-ons/extensions, and malicious website servers cause redirection.
Cybersecurity Essentials - Module 3: VPNs
-
VPNs: VPNs, or virtual private networks, encrypt data transmitted between two or more sites, making traffic unreadable to unauthorized parties. VPNs can be hardware-based or software-based.
-
VPN Types: Site-to-site VPNs connect two sites. Host-to-site VPNs connect a remote device to a site, and host-to-host VPNs connect two remote devices.
-
VPN Hardware Components: VPN hardware includes VPN concentrators, routers, and firewalls.
-
VPN Software Components: VPN software is integrated into software such as Windows OS or browsers (like Edge, Opera, or Firefox).
-
IPsec: IPsec is a set of network protocols that use cryptography to protect data travelling over the Internet, providing authentication and encryption. Its core components such as IPsec Authentication Header (AH) and Encapsulating Security Payload (ESP) are used for security.
-
Recap (VPNs): This module covers VPNs, their types (Site-to-Site, Host-to-Site, Host-to-Host), and the equipment components. Critical features also include protecting data through encryption and authenticating data.
