Network Security vs Cybersecurity – Explained

By IT No Comments

Difference between Network Security and Cybersecurity?

Similarities and differences between cybersecurity and network security are closely related.
Information security, network security, cybersecurity: the industry is flooded with terms to describe how companies protect their network data. While the experience of wading through a mixture of terminology to describe a specific operation or function is not limited to the network industry, the use of several terms complicates the process of developing an effective approach to secure data within the company.
In particular, confusion reigns over the differences between network security and cybersecurity. What is the difference between them? How are they alike? Let’s try to clear up the confusion.

What is cybersecurity?

 
Technically speaking, cybersecurity considers the security of the entire cybernetic continuum. In other words, it cares about protecting data within a company’s network computing space. In practice, this includes ensuring where data is stored, where it is handled and where it is transported. Simply put, cybersecurity refers to data protection, both at rest and on the move.
In practical terms, cybersecurity can be considered as the security of all computing space, from the information asset to the information user, including all intermediate components. The user does not need to be a human; As a result, cybersecurity also covers communications between data processing systems. That said, when IT professionals speak in terms of cybersecurity, they are usually more concerned with the security of the data that is stored and not transmitted.
In order to have a successful cybersecurity approach, there should be multiple layers of protection. People on the network must understand data security principles like not opening sketchy emails, backing up their data, and choosing strong passwords for their accounts. On top of that, there should be a policy on how cyber-attacks would be handled. People, processes, and technology should all be on the same page in order to achieve the highest level of cybersecurity.

What is network security?

 
In the company’s modern computing infrastructure, it is likely that the data is in motion and at rest. This is where network security comes into play. While technically a subset of cybersecurity, network security primarily deals with the company’s network infrastructure. It deals with topics such as securing the contour of the network; data transport mechanisms, such as switches and routers; and those pieces of technology that provide protection for data as they move between computing nodes. It delves into the details and security of every single gateway in a network that could be vulnerable to attack. Types of network security include antivirus software, email security, firewalls, and more.
Of course, all this raises the question: if network security is simply a subset of cybersecurity, why even subdivide the domain? One of the reasons is that cybersecurity tends to consider security, including the evaluation of technologies such as encryption. Encryption is important, but it does not necessarily have to do with the problems, companies face in protecting the network.
In addition, it is not always networking security versus cybersecurity, since the two complement each other in the data protection continuum. If one thinks in terms of data protection both at rest and in motion, then network security covers the data that travels through the network, while cybersecurity is concerned with protecting data at rest.

The critical difference between network security and cybersecurity

 
Where cybersecurity and network security differ is mainly in the application of security planning. A cybersecurity plan without a network security plan is incomplete; however, a network security plan can be independent.
Looking at this in another way, network security is a subset of cybersecurity, which, in turn, is a subset of information security, another separate issue. However, if you evaluate your security needs, the planning should be reduced to the lowest level. At each level, procedures and tools must ensure that access to confidential information is controlled and measures are taken to detect and mitigate any infringement that could lead to the disclosure of such information. Ultimately, the survival of a company could depend on the success in creating such a framework.

10 IT Buzzwords That You Need to Know in 2019

By IT No Comments

2019’s IT Buzzwords You Need to Know

There is no denying it; our world is advancing, and rapidly as a matter of fact. Along with technological advancements comes an entire slew of new words, vocabulary, and terminology.

For those unfamiliar with the advancements that have been taking place, a lot of the viral words of 2019 may seem like jibberish. We are here to break down some popular information technology (IT) buzzwords into manageable pieces so that they are easier to understand and conceptualize.

IT does not need to be an overwhelming or challenging topic; deeper explanation with clear wording can help. The same goes for 2019’s IT buzzwords; once broken down into bite-sized, easy to understand bits, their meanings become evident.

Viral words of 2019

The pace of IT developments are progressing rapidly, so it can feel difficult to keep up with all of the new accomplishments and advances.  This shortlist runs you through the IT buzzwords of 2019 you should know to be up-to-date with some of the most recent tech evolutions.

 

Artificial Intelligence

Sometimes referred to as merely ‘AI’, artificial intelligence is a term that can be seen extensively amongst tech news and other scientific developments. In short, artificial intelligence represents any machinery or software that is capable of human-like results and functions.

Artificial intelligence machines and software are sometimes even capable of learning as they operate, through a system of what is called artificial neural networks. The function of these self-learning devices is termed machine learning and it continues to pop up more and more in modern technological set-ups. Machine learning and artificial neural networks can be utilized to produce highly accurate results in an absurdly fast manner, as well as recognizing threats and challenges that would have gone overlooked by other, less complex networks or by human eyes.

Artificial intelligence can also refer to robots that are capable of learning as they operate. For this reason, there are some individuals that actually fear the future capabilities of artificial intelligence (AI), but for the time being it seems the applications of these devices are especially beneficial and advantageous.

Present-day examples:

Personal assistant programs (Alexa, Siri, Echo)

Social media face recognition software (Facebook)

Ridesharing applications (Uber, Lyft)

Email spam filters

 

Blockchain

There is a highly likely chance you have heard of Bitcoin. This buzzy term has grown to become the world’s most successful, albeit fragile cryptocurrency that has either garnered extreme enthusiasm, a complete dislike of, or indifference towards.

With cryptos such as Bitcoin growing to such mass popularity and profitability, there had to be a standard set into place. This is where the term blockchain comes into play.

Blockchain is, for example, what keeps Bitcoin traders from getting ripped off, by monitoring every transaction and maintaining strict records of all exchanges of Bitcoin. Everyone can see this transaction history, which is open source and available to anyone who wishes to glance upon the comings and goings of this cryptocurrency. Additionally, blockchain is naturally encrypted, which gives users a further sense of security.

This unique and clever system prevents counterfeit Bitcoin from being traded, which increases the cryptocurrency’s reputability and trustworthiness, but blockchain is not only limited to Bitcoin. In fact, this system can be set into place for any cryptocurrency and is often the structure of choice opted for. This new database is even being considered for use in banking and medical storage. Blockchain allows successful Bitcoin traders and other crypto collectors to rejoice, so be it that their trades are going well.

 

Mobile-First

Mobile-first is not exactly a new concept, and not as much a buzzword as it is a business model and developmental concept. In a world where the internet was first designed for desktop and then laptop use, it was not until the last decade with the release of the iPhone, one of the world’s most popular smartphones, that mobile compatibility became a high priority.

What mobile-first refers to now is a business model in which websites, applications, and other programs are developed first for use on mobile devices, and then afterward produced for computer use.

Even if companies are not agreeing to mobile-first philosophies, they are at least almost always assenting to mobile inclusive developments, because those that choose not to include mobile visitors in their demographics are asking to go out of business in this modern world.

Present-day examples:

These mega-companies are only a few that have taken on the mobile-first mindset.

Lululemon

Walmart

Domino’s

bareMinerals

 

3D Alteration

Since the arrival of 3D printers, this practice, sometimes referred to as additive manufacturing, has taken a number of industries by storm. Items and objects are produced through the generation and build-up of one layer after another, leading to a multi-dimensional final result that is tangible, unlike the 2D nature of most printed copies.

A number of materials can be created through 3D alteration, from metal, plastic, food, and housing to even human tissue. Due to its wide range of applications, both wealthy companies and startups have turned towards this technology to produce their desired results.

Present-day examples:

Nike

Ford

Boeing

MakieLab

DIY Rockets

General Electric

 

Internet of Things

The Internet of Things, also known as IoT, is a web of connections between machines, computing devices, people, and even animals that interact amongst one another to produce specific functions. Unique identifiers are created (UIDs), which then make it possible for data to be transmitted across networks without the need for human interaction with other humans or with computers.

This interrelatedness between machines and man has expanded across a multitude of industries, from wearables and mobile devices to auto, home, and environmental applications.

Present-day examples:

Home security systems

Smart electronic appliances

Household and commercial lights and thermostats

Speaker systems

Vending machines

Cars

 

Quantum Computing

Quantum computing is a method of data analysis in which computers become more capable of solving complex problems through the utilization of quantum bits, known as qubits. Compared with classic electronic selections that use the two defined states of either 0 or 1 known as binary digits or bits, this alternative is much more versatile but it presently has its limits.

As technologies continue to advance into the future, it can be expected that further applications for quantum computing will become a reality. Companies such as NASA are already interested in quantum computing in order to map mass amounts of data, such as information they compile pertaining to the universe. It doesn’t get much more vast than that!

 

Virtual Reality (VR)/Augmented Reality (AR)

Virtual Reality (VR) and Augmented Reality (AR) are closely related terms. Augmented Reality is, in some ways, a more simplified version of Virtual Reality, in which computer-generated aspects such as GPS data, various sounds, and videos are implemented alongside aspects of the real world. Probably the most accessible example of AR would be an application such as Pokemon Go. This game uses user location and positioning in order to create the map of the game, while applying its own computer graphics, such as when various Pokemon appear onto the screen.

Virtual Reality takes AR a step further by greater interacting with user senses. With Virtual Reality, you can essentially feel as if you have stepped into a completely different world, a digital yet highly real feeling version of whatever you would like to experience.

VR typically requires the consumer to wear sound-canceling headphones along with VR goggles. Sometimes arm toggles are also used to control the hand movements within the virtual world. The combination of these elements furthers the gamer experience by blocking them away from the outside world as much as possible.

In addition to providing an intriguing and realistic gaming experience, VR is also utilized for simulations in occupations that require expert training such as flying planes, surgery, and other complicated processes.

 

Immersive Experience

Related to VR and AR, these two aforementioned terms are actually considered a part of the immersive experience. An immersive experience is any type of circumstance that completely encompasses and engulfs the senses, as to take you away from reality for a moment and leave you feeling as if you actually exist within another world.

In truth, immersive experiences do not only need to relate to technology. Any event or undergoing that places you into what feels like an alternate universe for a moment of time is, by definition, an immersive experience. Attending an art show or concert, exercising, or focusing in a classroom can all fall under this category of being immersive.

 

Data Mining

Data mining is mostly how it sounds; this process is the discovery of the paradigms existent amongst mass amounts of data and information. Data mining alone does not involve the actual process by which data is mined, rather it is the overall concept. Instead, techniques used to mine data are described differently.

Some common techniques used in data mining include personalization, artificial intelligence (which we discussed earlier on), machine learning, and actionable analytics.

 

Net Neutrality

Net neutrality is not only a tech concept but is also tied in with political and governmental aspects. This term is the belief that all data and information available on the internet should be treated in the exact same manner, regardless of the government organization or the internet provider connected.

All tied into the idea of internet privacy, companies and government organizations can collect and track data to then pay money in order to prioritize their Internet traffic over another’s.

What this means, is that if an internet provider were to begin their own movie or music streaming company, the advertising and promotion of that service would then take priority over other established providers such as Netflix or Spotify, leading to a biased selection for potential customers.

Discussions about net neutrality are especially prominent currently in the United States, so those who reside in the US are encouraged to read more about the topic and gain a greater education on what it means to be net neutral.

Popular IT Buzzwords You Need to Know in 2019: Conclusion

Popular IT buzzwords of this year need not be overwhelming. In reality, for the average individual, these terms aren’t necessary to understand in great depth and detail but the general concepts can be valuable to grasp. Aside from this minute list of terms to know, with all of the tech advances happening each day it merely is not possible to keep up, but one can do their best and try to be as educated as possible.

Your Systems are Under Attack by Zombies, Bots, and Botnets

By IT No Comments

As the world shifts into more and more of a digital realm, physical threats are no longer the only concern. Now, for many, cyber-attacks are a much more relevant reality. The idea of security threats should not instill fear, rather it is simply an aspect of computer-use and internet surfing that should be always taken into consideration so that all can better protect themselves and in turn their personal information.

What Are Bots?

Bots, a shortened term used for programmed robots, are scripts or software apps that are designed to execute specific auto-pilot tasks. Although bots outside of the hacking world can be utilized for many valuable purposes such as automating user interaction and social media management, when in the wrong hands or applied by individuals with malicious intentions, these robots can become dangerous and a real security threat.

Bots are the core foundational tool utilized for remote cyber-attacks and they make up more serious implementations, such as botnets and zombies.

 

What Are Botnets and How Do They Work?

Botnets are networks of bots used to infect and upload malicious malware onto a chain of devices. Once a botnet has been implemented, the infected device then also becomes the infectee. This all takes place in extreme stealth mode, which is how botnet chains often go undetected, continuing to pose a threat to a long extension of systems.

In some cases, famous botnets have been able to infect many hundreds of millions of computers and networks, and even once they are thwarted they can be modified into new variations that continue to do damage. Because those with infected devices are often unaware of there being any breach of their technology, they can transfer the malware to others quite easily.

A master-bot is typically in charge of giving bots orders, and the bots often report back to manager-bots which then communicate with the master-bot. This system is highly organized and allows for the individual or individuals in charge to easily manage massive networks of botnets, all while remaining heavily under the radar. For this reason, generating botnets is a low risk, high reward undertaking that often proves to be very successful for those who develop solid malware.

One surprising fact about botnets is that the actual operations behind the attacks are minuscule in size, sometimes made up of only one or two individuals, yet the effects of such implementations are on a mass scale and often highly detrimental.

 

What Are Zombies?

Botnets, or a network of infected computers under attack remotely, are also referred to as zombie computers. Zombies or zombie computers, specifically, relate to the computers themselves that are capable of passing along malicious and risky security breaches.

 

What Do Hackers Gain from Cyber Attacks?

There are many reasons why hackers carry out cyber attacks such as zombie attacks, and most of the time it relates to financial gain. You see, information is often bought and sold on the internet, and commonly for a big price. By stealing personal and financial information, hackers receive compensation for any data they are able to provide to those who are interested.

Botnets can be used to generate intricate scams as well, tricking consumers into providing personal information, along with flat out handing over money. Additionally, those who don’t fall for these scams could be attacked unknowingly and identities can be stolen, which are then used for purchases and running up loans.

One of the worst ways a hacker or cybercriminal can use gained information for financial gain is by extorting money from unsuspecting victims by threatening them with a leak of personal information or compromising photos, documents, etc. This is a technique that has been used on large companies and organizations as a means of blackmailing them into cooperation. Often times, companies can do nothing more than agree to pay the sum, for thwarting a security breach like this is extremely difficult and requires an extensive team of specialists.

Cybercriminals also hire other cybercriminals for their own gain, leasing their botnets and further spreading compromising digital and internet infections across many platforms. For some, the financial gain received from a leased botnet system is far greater than what they are paying the initial zombie attack developer.

 

How Can One Know If Their Device Is Infected?

Because zombie attacks are often rather rogue, it can be challenging to know if any of your devices have been infected. A reputable anti-virus program usually can detect botnets and will alert you if it discovers an attack. Aside from this, there are at times signs that your computer could be impacted. If you experience your computer slowing down significantly, suddenly running its cooling fan without warning, or any other strange behaviors happening, there’s a chance your device has some sort of breach and should be cleaned up.

 

How to Better Protect Your Information

The absolute best way to minimize the chances of your device becoming compromised by a botnet or malicious zombie attack is by ensuring that your computer or network is protected with an up-to-date, highly reliable anti-virus, anti-malware, or internet security software. Luckily, there are many free programs that can do the trick but research is needed to decide which option is best for you and your devices. Run your anti-virus programs on a regular basis for a full-computer scan.

The next step after you have successfully implemented internet security software is to monitor your internet usage. Many attacks can be prevented by using discretion and common sense when browsing the web or downloading files. Never download files from unsecured sources or from individuals you do not recognize, even if you receive an attachment in an email. Do not click on links or download files sent by spam email addresses.

Finally, regularly change your passwords for your accounts. This can help to minimize the possibility of someone accessing your data or profiles and then applying a botnet or other security threat from within the account. Furthermore, regularly updating passwords and further securing your accounts can prevent any of your personal information from getting stolen, such as credit card numbers, social security numbers, home addresses, phone numbers, and more.

 

Understanding Zombies, Bots, Botnets, and Cyber Attacks: Summary

Remaining informed and in the loop with regards to the various extents of potential cyber-attacks is extremely valuable in this day and age when security breaches can affect literally anyone that uses a computer; oftentimes unknowingly and without warning. By understanding zombies, bots, and botnets along with what their presence entails, the proper measures can be set into place for successful cyber protection. Even those who are not interested in IT or computer-related details should be up-to-date with how to better protect confidentially and potentially compromising information.

Having a deep awareness of such threats is even more crucial for those entering careers in IT, software development, or programming because at some point you will likely come face to face with such security threats and the proper actions will need to be taken to foil any potential breaches.

Although there are many career colleges in San Diego, if you’re searching for IT schools or and affordable school for IT, ICOHS is a non-profit, accredited vocational college that offers programs for those fascinated by tech and our growing digital world.
