CYBERSECURITY KEY TERMS

1- Security Key Terms:

• • Cryptography:  Practice and study of techniques for secure communication in the presence of third parties called adversaries.

• • Hacking: catch-all term for any type of misuse of a computer to break the security of another computing system to steal data, corrupt systems or files, commandeer the environment or disrupt data-related activities in any way.

• • Cyberwarfare: Uuse of technology to attack a nation, causing comparable harm to actual warfare. There is significant debate among experts regarding the definition of cyberwarfare, and even if such a thing exists

• • Penetration testing: Colloquially known as a pen test, pentest or ethical hacking, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system. Not to be confused with a vulnerability assessment.

• • • Malwares: Any software intentionally designed to cause damage to a computer, server, client, or computer network. A wide variety of malware types exist, including computer viruses, worms, Trojan horses, ransomware, spyware, adware, rogue software, and scareware. 
  • Malware Analysis Tool: Any .Run Malware hunting with live access to the heart of an incident https://any.run/Malware Analysis Total:  VirusTotal – Analyze suspicious files and URLs to detect types of malware, automatically share them with the security community https://www.virustotal.com/gui/

• • VPN: A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running across a VPN may therefore benefit from the functionality, security, and management of the private network. Encryption is a common, although not an inherent, part of a VPN connection.

• • Antivirus: Antivirus software, or anti-virus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware.

• • DDos: A distributed denial-of-service (DDoS) attack is one of the most powerful weapons on the internet. When you hear about a website being “brought down by hackers,” it generally means it has become a victim of a DDoS attack.

• • Fraud Detection: Set of activities undertaken to prevent money or property from being obtained through false pretenses. Fraud detection is applied to many industries such as banking or insurance. In banking, fraud may include forging checks or using stolen credit cards.

• • Spywares: Spyware describes software with malicious behavior that aims to gather information about a person or organization and send such information to another entity in a way that harms the user; for example by violating their privacy or endangering their device’s security.
  • Spoofing: Disguising a communication from an unknown source as being from a known, trusted source
  • Pharming: Malicious websites that look legitimate and are used to gather usernames and passwords.
  • Catfishing: Creating a fake profile for fraudulent or deceptive purposes

• • SSL: Stands for secure sockets layer. Protocol for web browsers and servers that allows for the authentication, encryption and decryption of data sent over the Internet.
  • Phishing emails: Disguised as trustworthy entity to lure someone into providing sensitive information

• • Intrusion detection System: Device or software application that monitors a network or systems for malicious activity or policy violations. Any intrusion activity or violation is typically reported either to an administrator or collected centrally using a security information and event management system.

• • Encryption: Encryption is the method by which information is converted into secret code that hides the information’s true meaning. The science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext.

• • MFA: Multi-factor authentication (MFA) is defined as a security mechanism that requires an individual to provide two or more credentials in order to authenticate their identity. In IT, these credentials take the form of passwords, hardware tokens, numerical codes, biometrics, time, and location.

• • Vulnerabilities: A vulnerability is a hole or a weakness in the application, which can be a design flaw or an implementation bug, that allows an attacker to cause harm to the stakeholders of an application. Stakeholders include the application owner, application users, and other entities that rely on the application.

• • SQL injections: SQL injection is a code injection technique, used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution.

• • Cyber attacks: In computers and computer networks an attack is any attempt to expose, alter, disable, destroy, steal or gain unauthorized access to or make unauthorized use of an asset.

• • Confidentiality: Confidentiality involves a set of rules or a promise usually executed through confidentiality agreements that limits access or places restrictions on certain types of information.

• • Secure channel: In cryptography, a secure channel is a way of transferring data that is resistant to overhearing and tampering. A confidential channel is a way of transferring data that is resistant to overhearing, but not necessarily resistant to tampering.

• • Tunneling: Communications protocol that allows for the movement of data from one network to another. It involves allowing private network communications to be sent across a public network through a process called encapsulation.

• • SSH: Secure Shell is a cryptographic network protocol for operating network services securely over an unsecured network. Typical applications include remote command-line, login, and remote command execution, but any network service can be secured with SSH.

• • SSL Certificates: SSL certificates are what enable websites to move from HTTP to HTTPS, which is more secure. An SSL certificate is a data file hosted in a website’s origin server. SSL certificates make SSL/TLS encryption possible, and they contain the website’s public key and the website’s identity, along with related information.

• • Phishing: Phishing is a cybercrime in which a target or targets are contacted by email, telephone or text message by someone posing as a legitimate institution to lure individuals into providing sensitive data such as personally identifiable information, banking and credit card details, and passwords.

• • Cybercrime: Cybercrime, or computer-oriented crime, is a crime that involves a computer and a network. The computer may have been used in the commission of a crime, or it may be the target. Cybercrime may threaten a person, company or a nation’s security and financial health.

• • Backdoor: A backdoor is a means to access a computer system or encrypted data that bypasses the system’s customary security mechanisms. A developer may create a backdoor so that an application or operating system can be accessed for troubleshooting or other purposes.

• • Salt and Hash: A cryptographic salt is made up of random bits added to each password instance before its hashing. Salts create unique passwords even in the instance of two users choosing the same passwords. Salts help us mitigate rainbow table attacks by forcing attackers to re-compute them using the salts.

• • Password: A password, sometimes called a passcode,^[1] is a memorized secret, typically a string of characters, usually used to confirm the identity of a user.^[2] Using the terminology of the NIST Digital Identity Guidelines,^[3] the secret is memorized by a party called the claimant while the party verifying the identity of the claimant is called the verifier. When the claimant successfully demonstrates knowledge of the password to the verifier through an established authentication protocol,^[4] the verifier is able to infer the claimant’s identity.

• • Fingerprint: A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Moisture and grease on a finger result in fingerprints on surfaces such as glass or metal.

• • Facial recognition: Facial recognition works better for a person as compared to fingerprint detection. It releases the person from the hassle of moving their thumb or index finger to a particular place on their mobile phone. A user would just have to bring their phone in level with their eye.

• • Asymmetric key ciphers versus symmetric key ciphers (Difference between symmetric and  Asymmetric encryption): The basic difference between these two types of encryption is that symmetric encryption uses one key for both encryption and decryption, and the asymmetric encryption uses public key for encryption and a private key for decryption.

• • Decryption: The conversion of encrypted data into its original form is called Decryption. It is generally a reverse process of encryption. It decodes the encrypted information so that an authorized user can only decrypt the data because decryption requires a secret key or password.

• • Algorithms: Finite sequence of well-defined, computer-implementable instructions, typically to solve a class of problems or to perform a computation.

• • Authentication: is the act of proving an assertion, such as the identity of a computer system user. In contrast with identification, the act of indicating a person or thing’s identity, authentication is the process of verifying that identity. It might involve validating personal identity documents, verifying the authenticity of a website with a digital certificate,^[1] determining the age of an artifact by carbon dating, or ensuring that a product or document is not counterfeit.

• • DFIR: Digital forensic and incident response: Multidisciplinary profession that focuses on identifying, investigating, and remediating computer network exploitation. This can take varied forms and involves a wide variety of skills, kinds of attackers, an kinds of targets. We’ll discuss those more below.

• • • OTP: One Time Password: A one-time password, also known as one-time PIN or dynamic password, is a password that is valid for only one login session or transaction, on a computer system or other digital device

• • Proxy Server and Reverse Proxy Server:A proxy server is a go‑between or intermediary server that forwards requests for content from multiple clients to different servers across the Internet. A reverse proxy server is a type of proxy server that typically sits behind the firewall in a private network and directs client requests to the appropriate backend server.

CYBERSECURITY Q&A

How SSL Certificates Work

• A browser or server attempts to connect to a website (i.e. a web server) secured with SSL. The browser/server requests that the web server identify itself.
• The web server sends the browser/server a copy of its SSL certificate.
• The browser/server checks to see whether or not it trusts the SSL certificate. If so, it sends a message to the web server.
• The web server sends back a digitally signed acknowledgement to start an SSL encrypted session.
• Encrypted data is shared between the browser/server and the web server.

There are many benefits to using SSL certificates. Namely, SSL customers can:

• Utilize HTTPs, which elicits a stronger Google ranking
• Create safer experiences for your customers
• Build customer trust and improve conversions
• Protect both customer and internal data
• Encrypt browser-to-server and server-to-server communication
• Increase security of your mobile and cloud apps

 

Penetration Testing Terms

Penetration Testing Terms to know:

• Audit — Conduct a complete inspection of an organization’s network to find vulnerable endpoints or malicious software.
• Access Control List — A list that contains users and their level of access to a system.
• Aircrack-ng — Wifi penetration testing software suite. Contains sniffing, password cracking, and general wireless attacking tools.
• Backdoor — A piece of code that lets hackers get into the system easily after it has been compromised.
• Burp Suite — Web application security software, helps test web apps for vulnerabilities. Used in bug bounty hunting.
• Banner Grabbing — Capturing basic information about a server like the type of web server software (eg. apache) and services running on it.
• Botnet — A network of computers controlled by a hacker to perform attacks such as Distributed Denial of Service.
• Brute-Force Attack — An attack where the hacker tries different login combinations to gain access. eg. trying to crack a 9 -digit numeric password by trying all the numbers from 000000000 to 999999999
• Buffer Overflow — When a program tries to store more information than it is allowed to, it overflows into other buffers (memory partitions) corrupting existing data.
• Cache — Storing the response to a particular operation in temporary high-speed storage is to serve other incoming requests better. eg. you can store a database request in a cache till it is updated to reduce calling the database again for the same query.
• Cipher — Cryptographic algorithm for encrypting and decrypting data.
• Code Injection — Injecting malicious code into a system by exploiting a bug or vulnerability.
• Cross-Site Scripting — Executing a script on the client-side through a legitimate website. This can be prevented if the website sanitizes user input.

• Social Engineering — The art of tricking people into making them do something that is not in their best interest. eg. convincing someone to provide their password over the phone.
• Secure Hashing Algorithm (SHA) — Widely used family of encryption algorithms. SHA256 is considered highly secure compared to earlier versions like SHA 1. It is also a one-way algorithm, unlike an encryption algorithm that you can decrypt. Once you hash a message, you can only compare with another hash, you cannot re-hash it to its earlier format.
• Sniffing — performing man-in-the-middle attacks on networks. Includes wired and wireless networks.
• Spam — Unwanted digital communication, including email, social media messages, etc. Usually tries to get you into a malicious website.

CyberSecurity Post COVID-19

How does Covid19 affect cyber risk?

1. Increased distributed working: With organizations embracing work from home, incremental risks have been observed due to a surge in Bring Your Own Device (BYOD), Virtual Private Network (VPN), Software As A Service (SaaS), O365 and Shadow IT, as it could be exploited by various Man-in-the-Middle (MITM) attack vectors.
2. Reimagine Business Models: Envisioning new business opportunities, modes of working, and renewed investment priorities. With reduced workforce capability, compounded with skill shortages, staff who are focusing on business as usual tasks can be victimized, via social engineering.
3. Digital Transformation and new digital infrastructure: With the change in nature for organizations across the industrial and supply chain sector – security is deprioritized. Hardening of the industrial systems and cloud based infrastructure is crucial as cyber threats exploit these challenges via vulnerability available for unpatched systems.
4. With an extreme volume of digital communication, security awareness is lowered with increased susceptibility. Malicious actors are using phishing techniques to exploit such situations.

Re-evaluate your approach to cyber

• • Which cyber scenarios your organization appears to be preparing for or is prepared?

• •  Is there a security scenario that your organization is currently ignoring – but shouldn’t be?

• • What would your organization need to do differently in order to win, in each of the identified cyber scenarios?

• What capabilities, cyber security partnerships, and workforce strategies do you need to strengthen?

The organizations should reflect the following scenarios at a minimum and consider:

• • Which cyber scenarios your organization appears to be preparing for or is prepared?

• •  Is there a security scenario that your organization is currently ignoring – but shouldn’t be?

• • What would your organization need to do differently in order to win, in each of the identified cyber scenarios?

• • What capabilities, cyber security partnerships, and workforce strategies do you need to strengthen?

• To tackle the outcome from the above scenarios, the following measures are the key:

Inoculation through education: Educate and / or remind your employees about –

• • Your organization’s defense – remote work cyber security policies and best practices

• • Potential threats to your organization and how will it attack – with a specific focus on social engineering scams and identifying COVID-19 phishing campaigns

• Assisting remote employees with enabling MFA across the organization assets

Adjust your defenses: Gather cyber threat intelligence and execute a patching sprint:

• • Set intelligence collection priorities

• • Share threat intelligence with other organizations

• • Use intelligence to move at the speed of the threat

• Focus on known tactics, such as phishing and C-suite fraud.

• Prioritize unpatched critical systems and common vulnerabilities.

Enterprise recovery: If the worst happens and an attack is successful, follow a staged approach to recovering critical business operations which may include tactical items such as:

• • Protect key systems through isolation

• • Fully understand and contain the incident

• • Eradicate any malware

• • Implement appropriate protection measures to improve overall system posture

• • Identify and prioritize the recovery of key business processes to deliver operations

• Implement a prioritized recovery plan

Cyber Preparedness and Response: It is critical to optimize the detection capability thus, re-evaluation of the detection strategy aligned with the changing landscape is crucial. Some key trends include:

• • Secure and monitor your cloud environments and remote working applications

• • Increase monitoring to identify threats from shadow IT

• Analyze behavior patterns to improve detection content

Finding the right cyber security partner: To be ready to respond identify the right partner with experience and skillset in Social Engineering, Cyber Response, Cloud Security, and Data Security.

Critical actions to address

At this point, as the organizations are setting the direction towards the social enterprise, it is an unprecedented opportunity to lead with cyber discussions and initiatives. Organizations should immediately gain an understanding of newly introduced risks and relevant controls by:

• • Getting a seat at the table

• • Understanding the risk prioritization:

• • Remote workforce/technology performance

• • Operational and financial implications

• • Emerging insider and external threats

• Business continuity capabilities

Assessing cyber governance and security awareness in the new operating environment

Assessing the highest areas of risk and recommend practical mitigation strategies that minimize impact to constrained resources.

Keeping leadership and the Board apprised of ever-changing risk profile

Given the complexity of the pandemic and associated cyber challenges, there is reason to believe that the recovery phase post-COVID-19 will require unprecedented levels of cyber orchestration, communication, and changing of existing configurations across the organization.

CyberSecurity: Protect Yourself on Internet

• • Use two factor authentication when possible. If not possible, use strong unique passwords that are difficult to guess or crack. This means avoiding passwords that use of common words, your birthdate, your SSN, names and birthdays of close associates, etc.

• • Make sure the devices you are using are up-to-date and have some form of reputable anti-virus/malware software installed.

• • Never open emails, attachments, programs unless they are from a trusted source (i.e., a source that can be verified). Also disregard email or web requests that ask you to share your personal or account information unless you are sure the request and requestor are legitimate.

• • Try to only use websites that are encrypted. To do this, look for either the trusted security lock symbol before the website address and/or the extra “s” at the end of http in the URL address bar.

• • Avoid using an administrator level account when using the internet.

• • Only enable cookies when absolutely required by a website.

• • Make social media accounts private or don’t use social media at all.

• • Consider using VPNs and encrypting any folders/data that contains sensitive data.

• Stay away from using unprotected public Wi-Fi networks.

• • Social media is genetically engineered in Area 51 to harvest as much data from you as possible. Far beyond just having your name and age and photograph.

• • Never use the same username twice anywhere, or the same password twice anywhere.

• • Use Tor/Tor Browser whenever possible. It’s not perfect, but it is a decent default attempt at anonymity.

• • Use a VPN. Using VPN and Tor can be even better.

• • Search engines like DuckDuckGo offer better privacy (assuming they’re honest, which you can never be certain of) than Google which, like social media, works extremely hard to harvest every bit of data from you that they can.

• • Never give your real details anywhere. Certainly not things like your name or pictures of yourself, but even less obvious things like your age or country of origin. Even things like how you spell words and grammatical quirks can reveal where you’re from.

• • Erase your comments from websites after a few days/weeks. It might not erase them from the website’s servers, but it will at least remove them from public view. If you don’t, you can forget they exist and you never know how or when they can and will be used against you.

• With Reddit, you can create an account fairly easily over Tor using no real information. Also, regularly nuke your accounts in case Reddit or some crazy stalker is monitoring your posts to build a profile of who you might be. Source: Reddit

 Notable Hackers

History

• The Strange History of Ransomware
  The first ransomware virus predates e-mail, even the Internet as we know it, and was distributed on floppy disk by the postal service. It sounds quaint, but in some ways this horse-and-buggy version was even more insidious than its modern descendants. Contemporary ransomware tends to bait victims using legitimate-looking email attachments — a fake invoice from UPS, or a receipt from Delta airlines. But the 20,000 disks dispatched to 90 countries in December of 1989 were masquerading as something far more evil: AIDS education software.

How to protect sensitive data for its entire lifecycle in AWS

You can protect data in-transit over individual communications channels using transport layer security (TLS), and at-rest in individual storage silos using volume encryption, object encryption or database table encryption. However, if you have sensitive workloads, you might need additional protection that can follow the data as it moves through the application stack. Fine-grained data protection techniques such as field-level encryption allow for the protection of sensitive data fields in larger application payloads while leaving non-sensitive fields in plaintext. This approach lets an application perform business functions on non-sensitive fields without the overhead of encryption, and allows fine-grained control over what fields can be accessed by what parts of the application.
