• VPNs, SDPs, SWGs, and More: Top Cybersecurity Tools and Trends to Look out for as Businesses Reopen

    11/10/2020 at 12:02 0 comments

    As businesses reopen and restore to normal, they should be looking to secure remote access and protect endpoints. According to a Mckinsey report, cybersecurity niches that would be high priorities for spending include perimeter security, next-generation identity and access controls, and remote access, among others.

    This article examines how three specific technologies (one legacy and two emerging) are important for those specific aspects of cybersecurity going forward. 

    Virtual Private Network

    VPNs have been around for a long time and despite longings for new and more advanced tools, none of the latest emerging technologies have been able to fully cover the functionality of VPNs. In fact, VPNs are going to become more efficient and at the same time more secure going forward. This is due to the increasing adoption of zero-trust components to better protect endpoints. Likewise, AI and automation will have huge impacts on client VPNs.

    The coronavirus pandemic has imposed on us a new reality of work: remote. Apparently, as reported by multiple agents, global demand for enterprise VPNs rose in the wake of the pandemic. That was not surprising at all. From a cybersecurity perspective, remote working is very risky as it increases the attack surface, reduces network visibility, and escalates remote access vulnerability.

    VPNs, which are meant for securing connections, can quickly become attack targets themselves. Note that even before the pandemic, enterprise VPNs have been the targets of several DDoS and MitM attacks. 

    To avoid these, it is important to use VPNs like Surfshark with strong encryption. One of the advantages of VPNs over the latest security technologies is that they (the former) are easy to set up. And if you do have one, upon returning to full work schedules (whether remotely or physically), one of the foremost measures to undertake should be patching and updating the company’s VPN.

    Software-Defined Perimeter

    Data is the world’s most valuable resource and much of cybersecurity attacks are attempts to seize control of confidential data, particularly personally identifiable information. Because of the rising spate of data breaches, the cybersecurity world now turns towards zero-trust approaches for data security. 

    SDP is the leading technology established on zero-trust principles. Most access control tools grant access based on authenticating devices. VPNs and firewalls, for instance, validate IP addresses. On the other hand, SDP uses a need-to-know model where it authorizes users themselves instead of the devices.

    In addition, upon authentication, it does not grant access to the entire network infrastructure. Instead, the user only gains access to a personalized set of resources required for their work at the time. This greatly reduces the attack surface and the potential impacts of a breach, if one were to occur. 

    SDP is being hailed as the next-generation VPN, and that doesn’t seem far-fetched at all. As SDP adoption accelerates, its market size is estimated to increase at a CAGR of 33.67% over the next five years.

    Secure Web Gateway

    Whether you want to protect your employees from phishing scams or need to ensure that they use the web within the acceptable conditions defined by the company, an SWG provides a fitting framework. An SWG interfaces between a device and the internet, inspecting all traffic for filtering malicious content and enforcing the company’s cybersecurity policy.

    Call it an advanced firewall if you wish. After all, like a firewall, it is usually delivered on-premise or as a cloud-based SaaS application. In fact, SWGs are quite similar to Next-Generation Firewalls (NGFWs).

    The bigger an enterprise, the harder it is to secure its endpoints. It’s worse when employees work remotely. And cybercriminals are not relenting in their efforts, embedding malicious components in seemingly innocuous sources (such as fake but professional-looking websites) that are sophisticated...

  • Treatment Methods to a Clean and Safe Water

    03/26/2020 at 17:03 0 comments

    By nature, water is known to be pure as it is composed of strong bonds of hydrogen and oxygen. However, the water supply across the globe has to share space with other things such as organic materials, minerals, chemicals, and human-made pollutants. This brings about an undrinkable solution since it contains deadly bacteria and viruses, among other disease-causing agents. Therefore, for clean and safe water to drink and cook, water treatment is a requirement.

    Below are several water treatment methods you can add to your home; 

    1. Treatment by Chlorination

    Chlorination is a safe and effective way to disinfect water. If done correctly, it would make muddy water drinkable, by eliminating all pathogens in it. This method involves introducing chlorinated products such as chlorine tabs and bleach into the water to kill the micro-organisms contained in it. After the products have acted for around thirty minutes, the water remains so for a few days depending on the storage conditions since chlorine is non-volatile.

    2. Using the SODIS process

    The SODIS method is perfect for treating drinking water. It requires only sunlight and lightweight, transparent plastic bottles that are made from polyethylene terephthalate (PET). The clear PET bottles are filled with water and exposed to sunlight for about six hours. The UV rays from the sunlight kill germs like viruses, bacteria, and parasites. The method also works at low air and water temperatures and is mostly used in developing countries.

    3. Treatment by boiling

    This method is very straightforward since boiling is simple and fast to accomplish. It kills all germs and microorganisms present in the water. For effective results, you have to first filter or decant the water, then bring it to a rolling, bubbling boil. Boiled water may lack taste, but to solve that, you can vigorously shake the water to get it oxygenated or by adding a little salt in it.

    4. Using Various Kinds of Water Softeners

    Like it's the case with most Americans, hard water is something you have to encounter day in day out. Hard water can be a menace as it leads to damage to your dishes, kitchen appliances, and even the drainage system. It's for this reason that a water softener should come in handy. Today, there are many water softeners in the market, and picking the right option can be confusing for the first-timers. Luckily for you, you can find more information concerning the many options available using reviews. With a detailed analysis of the leading options in the market today, it's much easier to arrive at an option that suits your needs. Also, using the reviews, you can find an affordable gadget and one that is easy to operate. 

    Water softeners usually come in various forms and operate in various ways, which include; 

    • Ion exchange: this kind of softener works by eliminating calcium and magnesium ions and replacing them with sodium ions, which have none of the various kinds of calcium and magnesium. 
    • Salt-free: This gadget uses a filter to eliminate calcium, but doesn't work very well on hard water. It doesn't deal with the stubborn magnesium.
    • Reverse Osmosis: This gadget filters water through a semipermeable membrane that excludes as much as 98% of water contaminants. It is an expensive tool, and it uses a considerable amount of water. This device is very good at removing all chemical impurities, as well as calcium magnesium.

    5. Using distillation process

    This is one of the old school treatment methods that you can as well borrow if you are out of options. Here the said water is boiled, and the resulting steam is collected and cooled back to water in a separate chamber. The treated water is relatively free of many contaminants. Generally, distillation is used to supply water only for drinking or particular uses. Distillation units are point-of-use devices that disinfect water, reduce the concentration of toxic metals to remove some organic contaminants. Home distillation units are...
