The dynamic duo of data and machine learning engineering in cybersecurity
The Speaker :
John Benito JP, Senior Manager, Data Science & Engineering at Capital One
John starts by mentioning that in today's world data is stored everywhere whether its texts in our phones, pictures we take, our fitness tracker etc etc. Each & every activity we perform on our devices are being logged, extracted, transformed somewhere whether local or cloud. All these information are very sensitive information which need to be safeguarded from certain parties who are interested in this data for malicious use, Cybersecurity comes to play to make sure all of this data, devices are secure.
The malicious cyberattack activities could be carried out in different ways in order to achieve this critical data -
Phishing: Phishing attacks involve the use of fraudulent emails, messages, or websites to deceive individuals into divulging sensitive information such as passwords, credit card numbers, or personal data. These attacks often mimic legitimate sources, exploiting trust to trick recipients into taking actions that benefit the attacker.
Malware: Malware, short for malicious software, refers to any software designed to harm, disrupt, or gain unauthorized access to a computer system. This includes viruses, worms, trojans, spyware, and ransomware. Malware can infect systems through various means, such as malicious email attachments, compromised websites, or infected USB drives.
Ransomware: Ransomware is a type of malware that encrypts a victim's files or entire system, rendering them inaccessible until a ransom is paid. Ransomware attacks typically demand payment in cryptocurrency and can have severe consequences, including financial loss, data breach, and operational downtime.
Man-in-the-Middle (MitM) Attack: In a MitM attack, an attacker intercepts communication between two parties without their knowledge, allowing them to eavesdrop on or manipulate the exchange of information. This can occur in various scenarios, such as unsecured Wi-Fi networks, compromised routers, or malicious software.
Zero-day Exploit: A zero-day exploit targets vulnerabilities in software or hardware that are unknown to the vendor or the public. Attackers exploit these vulnerabilities before a patch or fix is available, making them particularly dangerous as there is no defense against them until they are discovered and mitigated.
DNS Tunneling: DNS tunneling is a technique used to bypass firewalls and exfiltrate data from a network by encoding it within DNS queries and responses. Attackers exploit vulnerabilities in DNS servers or use specially crafted malware to establish covert communication channels, allowing them to transfer sensitive information undetected.
Cryptojacking: Cryptojacking involves the unauthorized use of a victim's computing resources to mine cryptocurrency. Attackers inject malicious scripts or malware onto devices, exploiting their processing power to mine cryptocurrency for the attacker's benefit. This can lead to increased energy consumption, system slowdowns, and potential damage to hardware.
Cross-Site Scripting (XSS) Attacks: XSS attacks occur when attackers inject malicious scripts into web pages viewed by other users. These scripts can execute arbitrary code in the victim's browser, leading to various security vulnerabilities such as data theft, session hijacking, or defacement of web pages.
Social Engineering: Social engineering attacks manipulate individuals into divulging confidential information or performing actions that compromise security. This can include pretexting, phishing, baiting, or impersonation to exploit human psychology and trust relationships for malicious purposes.
Denial-of-Service (DoS) & Distributed Denial-of-Service (DDoS) Attacks: DoS and DDoS attacks aim to disrupt or disable the availability of a targeted system or network by overwhelming it with a flood of traffic or requests. These attacks can render services inaccessible, causing financial losses, reputation damage, and operational disruptions.
SQL Injection: SQL injection attacks exploit vulnerabilities in web applications that use SQL databases by inserting malicious SQL code into input fields. This allows attackers to manipulate database queries, access unauthorized data, modify or delete records, and execute arbitrary commands on the underlying database server.
How is Cybersecurity achieved?
Cybersecurity is achieved through a multi-faceted approach that encompasses various measures, including technical controls, administrative controls, and awareness and training programs. Each of these components plays a crucial role in protecting against cyber threats and ensuring the security of computer systems, networks, and data. Let's explore how each of these means contributes to cybersecurity:
Technical Controls:
Technical controls involve the implementation of security measures within the IT infrastructure to prevent unauthorized access, detect and respond to security incidents, and protect against cyber threats. These controls include:
Access controls: Implementing user authentication mechanisms, such as passwords, biometrics, or multi-factor authentication, to verify the identity of users and limit access to authorized individuals.
Encryption: Encrypting sensitive data both in transit and at rest to protect it from unauthorized access or interception by hackers.
Firewalls and intrusion detection/prevention systems (IDS/IPS): Deploying firewalls and IDS/IPS solutions to monitor network traffic, detect suspicious activities, and block malicious traffic.
Endpoint security: Installing antivirus software, anti-malware programs, and endpoint detection and response (EDR) solutions to protect endpoints, such as computers, laptops, and mobile devices, from malware and other cyber threats.
Patch management: Regularly applying software patches and updates to address security vulnerabilities and ensure that systems are up-to-date with the latest security fixes.
Administrative Controls:
Administrative controls involve the implementation of policies, procedures, and guidelines to manage security risks, establish accountability, and ensure compliance with regulatory requirements. These controls include:
Security policies and procedures: Developing and enforcing security policies and procedures that define acceptable use of IT resources, data handling practices, incident response procedures, and other security-related guidelines.
Risk management: Conducting risk assessments, identifying security threats and vulnerabilities, and implementing risk mitigation strategies to reduce the likelihood and impact of security incidents.
Incident response planning: Establishing incident response teams, procedures, and communication channels to effectively respond to security incidents, minimize damage, and restore normal operations.
User access management: Managing user accounts, permissions, and privileges to ensure that users have appropriate access levels based on their roles and responsibilities.
Security awareness training: Providing training and education programs to employees, contractors, and other stakeholders to raise awareness of cybersecurity threats, best practices, and compliance requirements.
Awareness and Training:
Awareness and training programs are essential for educating employees and stakeholders about cybersecurity risks and promoting a culture of security awareness within the organization. These programs include:
Security awareness training: Offering regular cybersecurity awareness training sessions, workshops, and online courses to educate employees about common cyber threats, social engineering tactics, phishing scams, and best practices for protecting sensitive information.
Phishing simulations: Conducting simulated phishing attacks to test employees' awareness and response to phishing emails, and providing feedback and training to improve their ability to recognize and report suspicious emails.
Security awareness campaigns: Launching awareness campaigns, newsletters, posters, and other communication initiatives to reinforce security messages, promote good security habits, and encourage reporting of security incidents.
What are the challenges faced in Cybersecurity ?
Cybersecurity faces an array of challenges in today's digital landscape, each presenting its own set of complexities and risks. Here's an overview of some prominent challenges along with their subtopics:
Evolving Sophisticated Attackers:
Advanced Persistent Threats (APTs): Sophisticated attackers, often state-sponsored or well-funded, employ APTs to infiltrate systems and remain undetected for extended periods.
Zero-day Exploits: Attackers leverage vulnerabilities unknown to the vendor or public, making them difficult to defend against until patches are developed. Remote work environments may introduce additional challenges in applying patches promptly across a dispersed workforce, leaving systems vulnerable to zero-day exploits.
Social Engineering: Attackers exploit human psychology to manipulate individuals into divulging sensitive information or performing actions that compromise security.
