Study Notes
What is Cybersecurity?
- Cybersecurity involves protecting systems, networks, and programs from digital attacks aimed at accessing, altering, or destroying sensitive information.
- Cyberattacks can also involve ransomware to extort money or disrupt normal business functions.
- Advanced Persistent Threats (APTs) have transformed enterprise security and altered attack strategies.
Scope of Cybersecurity
- Protects three core principles: Confidentiality, Integrity, and Availability (CIA).
- Confidentiality ensures only authorized users can access or modify systems and data.
- Integrity guarantees the accuracy and reliability of data.
- Availability ensures that systems and data are accessible when needed.
State of Today’s Intrusion
- Cybercriminals are often well-funded, motivated professionals linked to organized crime or nation-states.
- Current threats are highly sophisticated, targeting various enterprises and types of information.
- High-profile breaches are increasingly common, indicating a rise in successful cyberattacks.
Notable Cyber Attacks
- Comodo: In March 2011, a reseller's network breach led to the theft of nine digital security certificates, allowing impersonation of major websites.
- Adobe: In October 2013, hackers stole nearly 3 million encrypted credit card records and login data, exposing customer information.
- Canva: In May 2019, a breach exposed personal information, including emails and hashed passwords of 61 million users.
- Uber: The company concealed a 2016 breach where hackers stole data of 57 million users, for which they paid $100,000 to prevent data publication.
- Epsilon: In 2011, a breach of customer databases exposed names and email addresses, facilitating potential spear phishing attacks.
Warning: False Sense of Security
- Many organizations mistakenly believe only financial data needs protection, overlooking the value of other sensitive information.
- High-profile breaches like Epsilon and Comodo emphasize that valuable data held by partners can also be a target.
The Changing Face of Cybercriminals
- Cybercriminals have evolved from hobbyist hackers to organized criminals driven by substantial financial incentives.
- Modern attackers are characterized by:
- Increased resources for conducting attacks.
- Greater technical expertise and specialization.
- Enhanced organizational capabilities.
- Financial backing often stems from nations, criminal organizations, or radical groups, raising the stakes in cybersecurity.
