Computer and Internet Security – Why the Security of Your Computer is Vital

Have you ever quizzed yourself as to the reason why you have suddenly realized that it is essential that you have a proper computer security system in place? The reason is that simple. Your computer stores all of your important information, tools, databases, intellectual property and transactions. Therefore, it is vital that you learn as much as possible about computer and internet security as it is important that this information should not be breached.

Now, let us take two persons for instance, Person A and Person B. Person A has a computer which is connected to the internet. This computer is therefore vulnerable to hacking because it has the capability of storing personal information like credit card numbers, bank account details, etc. on it. Now, for Person B, his computer is connected to the internet but he does not have a firewall installed. Therefore, he is also vulnerable to hacking and other damages caused by computer viruses and spy wares. Hence, it is clear that Person A is more susceptible to hacking and therefore he needs to have a better computer security system than, for example, Person B who has no computer and so is not connected to the internet.

What you need is a firewall installed on your computer. (Just in case if you do not have one already, go down to where you can download some good firewall software and win your self a high reputation among yourself). When you have installed a firewall, you need to be sure that it is properly configured. This can be done by talking to any computer experts or simply by doing some quick research about how to configure the firewall.

The role of the firewall is to monitor or filter traffic between the internet and your PC by using a series of rules. So, when you connect your computer to the internet, you run the risk of some unsolicited websites and stuff entering your PC unwantedly.

URL filtering is one way to fight this problem. It is a blocking function that allows you to block certain websites based on their URL. For example, you may be trying to view a certain website and an banner may pop-up so you can’t do so. If you want to view the site, you can choose another URL. Thus, both you and your computer is secured from a dangerous and unsolicited hacker.

To be able to achieve a good internet security, you need to follow some simple steps. These steps would not be so difficult if you have a simple program installed for the purpose. Basically, the program is in two functions; one, an entry point (which is your computer on the internet) and second, the filter/decider.

Proxy is used to filter internet traffic and this is a basic function of any good program. What is more, it is necessary to install a proxy program because the purpose of the second function is to monitor internet traffic to a limited extent and only after a certain amount of time, the website will be banned. You can’t be allowed to view a certain website; therefore, you’ll need a third party program to install a proxy website.

For alternative reasons, you can also try using “anonymous proxy servers”. These servers don’t proclaim to be anonymous and they may be bothering you with their presence. Sometimes, they cause hinderances to your PC as they are websites run by hackers and they want to monitor your online activities. If you use this server, make sure you download its source code and try running it.

Because, this software is free, you can try it and you’ll find that not only is it good for you but that it’s also free of charge. If you’re really considering it, make sure you can run it from your computer as the sources are not trustworthy.

The importance of 5G and communications has never been greater. They are essential for smooth video conferencing and remote working. In any event, thanks to the numerous benefits that we can have over others, such as 4G, this technology that is already with us presents itself quite effectively. This time, you’ll start with the most essential ones you’ve never heard of. Did you know it’s possible to save lives with it?

5G, a far more superior experience

While past generations of communications technology were focused on ensuring connectivity, 5G technology takes connectivity to the next level by providing customers with cloud-connected experiences. As a result, these networks are virtualized, run on software, and make use of cloud computing.

With seamless open roaming capabilities between the smartphone and our devices, as well as WiFi access, the 5G network facilitates mobility. Users can stay connected while travelling over external wireless connections and intra-premise wireless networks without requiring user intervention or, in some cases, re-authentication.

To achieve that speed, 5G use greater frequencies than prior networks, which is one of the benefits of the technology. Higher frequencies have the disadvantage that their signals do not go as far and are therefore more easily blocked by structures. But in what other ways can it help us?

Advantages we Have with 5G

In any case, while it is true that the nascent 5G technology, which could take a decade to fully develop, will have a greater influence on the industrial sector than on interpersonal communications, the transition from 4G to 5G will bring significant improvements and benefits to users.

Higher download speeds, the ability to connect more devices at once, and a faster response time from the moment an instruction is issued to an electronic device until it is implemented are just a few examples. The same can be said for some of the advantages we will notice in our daily lives. We can see the following among them.

A far Faster Speed

The biggest benefit of 5G technology, and the one that stands out the most among all of its benefits, is speed. It accomplishes this by considerably outperforming current fiber optic networks, with speeds of up to 10 Gbps allowing you to access high-quality digital content without interruption.

No Latency

Thanks to 5G, latency, or server wait time, is now nearly invisible. And, if we go beyond holding a phone in our hands, we will be able to test its utility in the not-too-distant future. Because of this reduction, real-time connections between an autonomous vehicle and traffic management centers will be possible.

It will let the car to respond swiftly to any occurrence in complex city driving scenarios, for example, and assess the options available. When you are not driving, the automobile will not be able to skip a red light.

More connected devices

One of the key advantages of this technology in the residential sphere is that it will allow more devices to be connected without reducing the quality of communications. And it’s apparent that an increasing number of smart houses that use home automation require very fast networks.

It’s very important to be able to provide a competitive reaction on a daily basis in a variety of settings. With this, and according to the most recent information from the operators, 5G is expected to be capable of supporting 1 million connected devices per square kilometer as soon as it is completely operational.

Saving lives remotely? It is possible

Surely you were unaware of this, but it is true. Because this technology allows us to save lives. This is because it can execute surgical operations remotely thanks to its speed and absence of delay. Last year, an example was presented of a surgeon in London, whose patient was a banana, and who was operating in a California operating room.

In real time, the doctor was able to perform a suture. We can appreciate the value of 5G if we consider the possibilities of saving lives in a short amount of time without the need for a specialized medical team to travel. And saving lives can be accomplished in a variety of ways, one of which is through firefighting. Drones outfitted with this technology will be able to provide georeferenced data, heat maps, and the human team’s disposition in front of a fire. Waiting times will be decreased, and a fire will be put out faster.

New Methods of Purchase and Security

5G will also allow us to put our devices to new applications. The shopping experience in stores could be enhanced by augmented reality, which can provide information on a food’s nutritional worth just by aiming the camera at it. Wearables will so provide medical-level health monitoring in conjunction with health clinics.

It also comes in handy for connecting household devices. As a result, having a home automation system with WiFi is a danger due to the insecurity of this technology. As a result, upgrading to 5G provides us with better reaction times, higher quality, and, most importantly, increased security.

The 14 ports on your Router that you should not open for the BEST Security

Published

Ports
Advertisements

All programs redirect their traffic through specific ports when we connect to the Internet. While some ports (such as 80 for Internet browsing) are open by default, the majority of ports are closed. At least 14 of them should still be that way, according to a recent security analysis.

These security flaws in your router’s 14 ports were discovered through a penetration test (pentest), which is a type of ethical hacking that involves performing authorized simulated cybersecurity attacks on websites, mobile apps, networks, and systems in order to find vulnerabilities using cybersecurity strategies and tools.

Why is it necessary to open ports?

In many cases, opening the router ports is required for our connection to function effectively. It may be vital to have specific ports open when using certain tools or programs, especially if we want them to work as well as possible.

Online games, chat or communication tools, download and torrent programs, and server configuration are examples of these tools. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are the two most prevalent forms of network protocols (UDP).

Ports that should remain closed

Let’s see which ones are regarded low-hanging fruit in penetration tests, keeping in mind that not all open ports are vulnerable, albeit locked ports are a lesser vulnerability in comparison. That is, security flaws that are simple to exploit.

FTP ports (20, 21)

File Transfer Protocol (FTP) is an acronym for File Transfer Protocol. TCP-only ports 20 and 21 are used to allow users to send and receive files from a server to their PCs.

Anonymous authentication, cross-site scripting, password brute force, and directory traversal attacks can all be used against the FTP port, which is unsecure and outdated.

SSH (22)

Secure Shell (SSH) is an acronym for Secure Shell. It’s a TCP port that’s utilized to provide secure remote server access. To get access to the target system, exploits can be carried either by brute-forcing SSH credentials or utilizing a private key.

SMB (139, 137, 445)

Server Message Block (SMB) is an acronym for Server Message Block. It is a Microsoft-developed communication protocol that allows users to share files and printers over a network. It might be abused using the EternalBlue vulnerability, brute-forcing SMB login credentials, NTLM Capture to exploit the SMB port, and PSexec to connect to SMB.

DNS (53)

Dns is the abbreviation for Domain Name System. It’s a TCP and UDP port that’s utilized for both transfers and queries. A Distributed Denial of Service (DDoS) attack is a typical DNS port exploit.

SQL injections, cross-site scripting, cross-site request forgery, and other attacks are all possible.

Telnet (23)

The Telnet protocol is a TCP protocol for connecting to remote computers over the Internet. Although SSH has largely replaced it, some websites continue to utilize it. It’s unsafe, outdated, and subject to malware, phishing, credential detection, and credential brute force.

TFTP (69)

A simplified variant of the File Transfer Protocol is TFTP, or Trivial File Transfer Protocol (FTP). It’s a UDP port that’s used to send and receive files via a network between a user and a server, therefore it’s vulnerable to password spraying, unwanted access, and denial of service (DoS) attacks.
