Nist Cybersecurity Framework: A Cheat Sheet For Professionals

Virtual Session: NIST Cybersecurity Framework Explained

The US National Institute of Standards and Technology’s framework defines federal policy, but it can be used by private enterprises, too. Here’s what you need to know.

The tech world has a problem: Security fragmentation. Theres no standard set of rules for mitigating cyber riskor even languageused to address the growing threats of hackers, ransomware and stolen data, and the threat to data only continues to grow.

President Barack Obama recognized the cyber threat in 2013, which led to his cybersecurity executive order that attempts to standardize practices. President Donald Trumps 2017 cybersecurity executive order went one step further and made the framework created by Obamas order into federal government policy.

The framework isnt just for government use, though: It can be adapted to businesses of any size.

TechRepublics cheat sheet about the National Institute of Standards and Technologys Cybersecurity Framework is a quick introduction to this new government recommended best practice, as well as a living guide that will be updated periodically to reflect changes to the NISTs documentation.

Hids Vs Nids: Are They The Same

Are students prepared for real

HIDS are host-based intrusion detection systems while NIDS are network-based intrusion detection systems. Because HIDS can detect malicious data packets originating from within the enterprise network, these systems are useful for catching inside threats. HIDS reviews historical data to identify unconventional cyberattacksunusual host-based actions changes to system files will trigger an alert. NIDS, however, detect threats in real-time through live data tracking of network traffic, meaning NIDS can catch hackers before a complete system breach occurs.

How Do You Differentiate Between Viruses And Worms

While viruses attach to a file or program, worms exploit network vulnerabilities to enter a network. Viruses only replicate when activated by a host, and will remain dormant in a system until an action is taken to trigger execution. Conversely, worms propagate independently after breaching a system and can spread without human interaction or the assistance of a host.

How Long Would You Wait Before Deploying A Critical Update

NIST Cybersecurity Framework

There are two schools of thought about critical updates. One is that any update that is considered critical needs to go out immediately to prevent any further damage. The other is that we must wait to ensure that the cure doesnt cause more problems than what its fixing. In either scenario, we want a test environment to ensure everything works as expected before deploying to production whenever possible.

I say whenever possible because 90% of the time, this is the responsible thing to do especially if the product we are patching may not have the best track record for updates being all good right out of the gate. Sometimes we have to wait for the update to the update to the update to the hotfix before it actually does what its supposed to do. However, the other 10% of the time, something in our environment DEMANDS this fix, and we desperately need it right now.

We also need a way to revert out of it, though, if things go utterly sideways.

Which Is More Secure Ssl Or Https

  • SSL is a secure protocol that provides safer conversations between two or more parties across the internet. It works on top of the HTTP to provide security.
  • HTTPS is a combination of HTTP and SSL to provide a safer browsing experience with encryption.
  • In terms of security, SSL is more secure than HTTPS.

What Is A Siem

SIEM is Security Information and Event Management software that provides a holistic view of what is happening on a network in real-time and help cybersecurity analyst to be more proactive in the fight against security threats.

SEM security event management carries out analysis of the event and logs data in real-time to provide event correlation, threat monitoring, and incident response

SIM security information management retrieves and analyses log data and generate a report. For the organization that wants complete visibility and control over what is happening on their network in real-time, SIEM solutions are critical.

How Does SIEM work?

SIEM collects log and event data that is generated by host systems, security devices, and applications throughout an organizations network infrastructure and collating it on a centralized platform. From antivirus events to firewall logs, SIEM software identifies this data and sorts it into categories, such as malware activity, failed and successful logins, and other potentially malicious activity.

When software identifies activity that could signify a threat, alerts are generated to indicate a potential security issue. These alerts can be set either low or high priority using pre-defined rules.

SIEM solutions provide a powerful method of threat detection, real-time reporting, and monitoring, long term analytics of security logs and events.

Can You Explain Tcp Three

The TCP three-way handshake is the method used in a TCP/IP network to create a connection between a local host/client and server. It is a three-step method that requires both the client and server to exchange SYN and ACK packets before actual data communication begins.

A client node sends an SYN data packet over an IP network to a server on the same or an external network. The objective of this packet is to ask/infer if the server is open for new connections.

The target server must have open ports that can accept and initiate new connections. When the server receives the SYN packet from the client node, it responds and returns a confirmation receipt the ACK packet or SYN/ACK packet.

The client node receives the SYN/ACK from the server and responds with an ACK packet. Upon completion of this process, the connection is created and the host and server can communicate.

Cybersecurity Is An Organizational Problem Not Just A Technical Problem

New NIST Guidelines Acknowledge Were Only Human

Many cybersecurity problems occur because of human error. A study from Stanford University revealed that 88% of data breach incidents were caused by employee mistakes. Aligning all employees, not just the cybersecurity team, around practices and processes to keep the organization safe is not a technical problem its an organizational one. Cybersecurity requires awareness and action from all members of the organization to recognize anomalies, alert leaders, and ultimately to mitigate risks.

Our research at MIT suggests this is best done by creating a cybersecurity culture. We define a cybersecurity culture as an environment infused with the attitudes, beliefs and values which motivate cybersecurity behaviors. Employees not only follow their job descriptions but also consistently act to protect the organizations assets. This does not mean that every employee becomes a cybersecurity expert it means that each employee is held accountable for overseeing and behaving as if he or she was a security champion. This adds a human layer of protection to avoid, detect, and report any behavior that can be exploited by a malicious actor.

Whats Your Ideal Next Step

We all have our dreams and desires, and often we try to fit what we want into someone else’s container because we don’t see the right container in front of us, Clark says. When we can get a well thought-out answer to this question, it can open up possibilities and opportunities that may not have been obvious before.

People change jobs to get closer to feeling as if they are living out their purpose, Clark says, and companies should want to know as much about that purpose as possible in order to ensure there is a right match, particularly in when making critical hires.

Why Is Cybersecurity In Demand

First and foremost, cyberattacks are costlyin fact, data breach costs rose to $4.24 billion per incident in 2021. As a result, many companies are investing in cybersecurity to skirt revenue loss and maintain customer trust. Digital transformation has touched every industry, and assets ranging from online financial transactions to industrial IoT-enabled machinery are now vulnerable to exploitation. As a result, cybersecurity regulations are growing, motivating organizations to protect their data and stay up-to-date with evolving legislative mandates.

Black Hat Hackers Vs White Hat Hackers Vs Grey Hat Hackers: Are All Illegal

Black hat hackers use cybersecurity knowledge to gain unauthorized access to networks and systems for malicious or exploitative ends. This type of hacking is illegal. Conversely, white hat hackersalso known as ethical hackersare hired to evaluate the vulnerabilities of a clients system. Because white hat hackers operate with the permission of their targets, this activity is legal. Grey hat hackers may search for system vulnerabilities without permission, but instead of exploiting the vulnerability directly may offer to fix the issue for a price. Because the intrusion was not permitted, grey hat hacking is often considered unethical and illegal.

What Is Referred To As A Man

NIST Cybersecurity Framework Overview

A man-in-the-middle attack occurs when a bad actor interferes with communications between two parties and monitors or manipulates the traffic traveling between them. Man-in-the-middle attackers are able to passively eavesdrop on the connection or actively intercept the connection in order to reroute traffic to another destination. The goal of such attacks may be to steal information or corrupt data, among other motivations.

What Do You Mean By A Vpn

A virtual private network establishes a protected network connection when using a public network. A VPN can encrypt internet traffic in real-time, thereby securing data that travels across the network and preventing third parties from tracking user activity. VPNs redirect a users IP address through a remote host server, allowing for IP address concealment.

Distinguish Among Threat Vulnerability And Risk


Classifying something as a threat should have potential and adverse effects on the company that could cause damage to the computer system, including the network, server, or company as a whole. A threat can appear in any form as an individual, technology in a malware form, or even natural disasters.


This can also take many forms, such as an unpatched server, weak passwords, an open port on an unmonitored computer on your network, etc. Vulnerability is a gap in the system security protocols which is an open gate for various attacks and breaches. Cybercriminals can use this to gain unauthorised entry, thereby causing security breaches.


The worst-case scenario is the risk that can happen when a threat is carried out against vulnerability on the network. This is potential damage to the company and is used to help motivate any security-related issues to be detected, prevented, or corrected.
