A firewall is a network security mechanism or layer of protection that sits between the internet and computer networks. An internet firewall can be described as a piece of hardware or software that safeguards the computer from unwanted data and viruses.

What is a Hardware Firewall at any NOC (Network Operations Center)?

A hardware firewall is a physical device that filters traffic to a computer, similar to a server. A network cable is generally hooked straight into a computer or server, however, with a hardware firewall, the cable is first plugged into the firewall. The firewall acts as an antivirus solution and a hard barrier against intrusions by sitting between the external network and the server. When put between a modem and wireless router, it helps stop attacks from reaching the devices and appliances.

What is a Software Firewall at any SOC (Security Operations Center)?

A software firewall is a sort of computer program that operates on a computer or server. Its main goal, depending on the software firewall being used, is to safeguard the computer/server from outside efforts to control or acquire access to the system. Any questionable outbound requests can also be checked with a software firewall.

Differentiating Hardware firewalls and Software firewalls based on their advantages

Hardware firewalls let a user use a single physical device to secure the whole network from the outside world. This gadget is connected to the internet through a computer network. A hardware firewall tracks data packets as they go over the network. According to established criteria, the firewall subsequently either blocks or sends the data. Installing dedicated hardware firewalls necessitates significant IT skills, and businesses require dedicated IT staff or department to monitor and manage hardware firewalls. As a result, hardware firewalls are typically used by large businesses or businesses that place a premium on security. Most routers nowadays feature rudimentary firewall functionality, however, these solutions are aimed at home or small business users.

Software firewalls, on the other hand, provide network internal protection. A software firewall is a piece of software that is placed on a single computer and serves to safeguard it. If a business needs to secure many computers, it will need to install the program on each one. A software firewall regulates how certain programs should behave. The administrator can, for instance, restrict access to specific websites or a network printer.

Why do organizations need to deploy both hardware and software firewalls?

A physical firewall protects a network from the outside world, whereas a software firewall protects a specific device from other devices connected to the network systems. If someone tries to access the systems from the outside, the physical firewall will stop them. However, if a user mistakenly opens a virus-infected email that has already entered the system, the software firewall on the workplace network may prevent the virus from infecting other workstations.

In some cases, due to the sensitive data being generated (for example in the healthcare and financial services industries), both firewalls will be used. The PCI DSS also requires both hardware and software firewalls (Payment Card Industry Data Security Standards).

In terms of software, one way to think about it is on a spectrum from ease to security. Hardware firewalls prioritize security over convenience in terms of buying, setup, and application. When used correctly, the two can work together to counteract others’ flaws while promoting their positive qualities.

What about tiny businesses that aren't as concerned about security? It's tempting to go with the simplest firewall to set up but it is important to know that firewalls, both hardware, and software, defend against a variety of dangers. Software firewalls evaluate network traffic that gets past the hardware firewall, whereas hardware firewalls prevent malware from accessing your network. Most IT experts believe that all businesses should use a combination of hardware and software firewalls to improve network security.

Why should you secure your IoT devices?

Widespread digitization has increased the convenience of using the internet, but it has also increased the risk of being targeted by cyber-attackers. Hackers can steal and exploit your personal and financial information, as well as take control of smart cameras and microphones to spy on you. As a result, your privacy and security may be jeopardized.

How to easily secure IoT devices?

Here are the seven ways to secure your IoT devices: -

Router configuration

Router ties all your IoT gadgets together and makes them useful. Don't use the default name for your router which is generally set by its manufacturer. People might find the default login and password and get access to your smart home network (if they discover the brand and model). So, set some strange name that has nothing to do with you or your place. Your router name must be very unique; also avoid revealing any personal information.

Strong access credentials

Set the router's password to something genuinely unique. Use passwords that are made up of a combination of letters, numbers, and symbols. The login credentials used to log into your IoT devices must also be set complicated. It's now critical to set unique set of credentials for each IoT device's user account and smartphone or web application. This ensures that even if one device's password is hacked, the other IoT devices remain secure.

Wi-Fi Network isolation for IoT wearables and gadgets

Many routers support guest network creation. It is advised to protect the primary home network from IoT cyber risks. You can build and deploy a secondary WiFi network. This will be devoted just to the IoT wearables and gadgets. Now, the IoT gadgets are operating via an isolated WiFi network. Hence, even if the hackers intrude, they would not be able to hack into your other vital personal devices.

Disable any features that you aren't using

Many IoT gadgets allow you to control them from any location on the earth. Disable remote access if you only use them on your home's Wi-Fi connection. Smart speakers, too, include Bluetooth alongwith a Wi-Fi connection. What if you don't utilize it? It should be turned off. It may sound weird, but an active microphone might be utilized to listen in on your chats if it is hacked. As a result, deactivating features entails blocking as many of those various entry points as feasible.

Updating and patching devices

Updating the firmware on your IoT devices may not happen automatically. Essential security patches are frequently included in these updates. So, do a manual check every few months and, if any outstanding firmware upgrades are discovered, install them without any delay.

Enable 2FA and MFA

Having a password plus an MFA (Multi-Factor Authentication) adds an extra degree of protection. When someone tries it hard to log in the IoT devices using 2FA (Two-Factor Authentication), they must offer extra evidence of identification every time. This proof could be an OTP or a verification code delivered to your phone or email address. MFA is activated by-default on most of the IoT devices in the market. You can use third-party apps like Google Authenticator to activate 2FA.

Installing an NGFW

A typical firewall lacks the essential security functions such as intrusion prevention and virus protection. Sometimes intercepting the SSL/SSH content and QoS management services aren’t available on traditional firewalls. The NGFW (Next-Generation FireWall) is an integrated network platform that combines a standard firewall with additional security features. An NGFW also contains almost all the features of a typical firewall. This makes it effective at detecting and defending against cyberattacks. NGFWs are an expensive investment, but the amount of security increment they provide for your IoT device network makes it quite worthwhile.

Even if you get the costliest IoT equipment from the most prestigious firms, the safety and security of your IoT devices’ network is ultimately in your own hands.

Privacy, securing data, and providing end-to-end security are unquestionably important components of doing business with clients online. The dynamically changing expectations and habits of online customers’ demands adoption of the best practices of securing user data and guaranteeing seamless user journeys. Some of the ways by which online businesses can secure their customer information are:

1. Tell the customer how the business uses their personal information - Customers may be cautious to share personal information with brands, owing to a lack of transparency between businesses and customers over how their data is handled. Transparency may go against traditional business practices. But being transparent brings genuine value to products and services while boosting brand loyalty in the current business-consumer connection. Customers can understand and subscribe to the wider picture if you are honest about how you use their data.
2. Check the IT environment for vulnerabilities and patch them - Businesses, particularly eCommerce sites, should test their sites on a regular basis to find vulnerabilities that aren't detected by their current security measures. Businesses must hire cybersecurity specialists or ethical hackers to identify code vulnerabilities. Running daily scans to ensure that malware hasn't been planted on the site is a basic check to be done. Businesses are also advised to invest in more powerful security programs as well.
3. Monitor and control the access to customers’ data - Software to assist the integration of devices into IT infrastructures provides extra security layers for login processes. It also provides tools to encrypt emails. While these tools can help prevent unwarranted attacks, they don't address the source of the problem. Human employees and their unpredictable behavior is the most concerning factor. The greatest strategy to reduce the risk to your data is to educate your employees about your company's data protection policies. No amount of technology innovation can insulate a business from human error and oversight. Employees must be educated about the ways to handle sensitive customer information. They must also undergo specific courses that train them in preventing classified corporate information from falling into the wrong hands. The staff must be made to think twice about sending sensitive information over email. Also, the IT teams must ensure that passwords are changed and updated on a regular basis.
4. Encryption is the need of the hour - Less than half of firms say they encrypt critical data, indicating that it is still a serious flaw. Payment processors such as Visa and MasterCard require retailers to encrypt card information by default during transactions. If the personal data is saved on corporate servers, there is a substantially higher danger of getting it hacked. The data has to be safeguarded with rigorous industry-standard security and the newest encryption technology.
5. Proactively prepare for a disaster and be resilient - Most businesses have a disaster recovery strategy in place to deal with human error, data center outages, and natural disasters, but cyber-attacks are sometimes overlooked. It's critical to put protections in place to ensure business continuity even after facing a data breach. Care must be taken to ensure cyber-attacks must not be able to disrupt day-to-day business operations.

It makes sense to invest the time and resources necessary to protect sensitive customer data. Businesses must build a culture of joint responsibility for securing data. Data breaches are on the rise, and their impact is expected to be seen for years to come. As a result, criminals are getting wiser about hacking their target networks. Companies are advised to prioritize customer data protection now more than ever.

Deepfake is a type of artificial intelligence created by combining the phrases deep learning and fake that facilitates in developing videos that have been fabricated via using deep learning techniques. It is a subset of AI that refers to algorithms that can learn and make intelligent judgments without human intervention. A deep-learning system can create convincing impersonations by examining images and videos of a target person from various perspectives and then copying their behavior and voice patterns. Once a prototype fake has been created, GANs (Generative Adversarial Networks) are used to make it more credible. The GANs method aims to find faults in the system and make adjustments to fix them.

How can you stay away from deepfake videos?

1. Deepfake videos are much simpler to spot than deepfake photographs. And you may accomplish so with the assistance of two factors. When a deepfake video of a person is created, for example, there is little difference between the person and the backdrop. However, you may spot a false video if the attention is solely on the face in the video and the surrounding is purposefully obscured.
2. Deepfake can be easily avoided by restricting personal images on social media and avoiding close-up photos of your face as much as possible.
3. Advanced artificial intelligence algorithms are under development which can swiftly identify deepfake videos thereby preventing people from falling prey to fake news and fake films.

When and where did deepfake start?

Deep Fake was a user on Reddit in 2017 who began employing face modification technology for pornography. It was from here that the term Deepfake was coined, and videos like this were known as Deepfake Videos. 

Deepfake as a boon to technology

MyHeritage, a software program, has been in the headlines for transforming any image into a 10-second movie. With this app, you may also breathe new life into old images using this program. With the use of this program, images of prominent personalities from past were transformed into movies. And these films show that if Artificial Intelligence is applied correctly, this approach may be beneficial to humans.

Deepfake as a threat to humanity

A.  Deepfakes were used to subvert democracy in the United States 

Facebook decided to prohibit the use of deep fakes after fake videos of politicians began spreading on social media. They allowed a few loopholes, such as the ability to keep sarcastic films and photos, but distinguishing between satire and agenda-driven content is difficult.

B.  Deepfakes began to be exploited by internet predators 

People began leveraging the ability to substitute anyone's face in an image or video to make pornographic content without their consent. As the deep fake technology allows them to do so by replacing face and expressions; all cybercriminals need is a profile photograph on social media to produce fake material to produce fake videos.

C.  Deepfake to tarnishing reputation of individuals 

A Pennsylvania mom, for example, was prosecuted for harassing cheerleaders at her daughter's school by employing deep fakes. The mother used manipulated recordings to carry out a cyberbullying campaign against girls she viewed as competitors to her daughter.

Deepfakes still continues pushing the digital media envelope where researchers suggest using NFTs (Non-Fungible Tokens) is the most effective strategy to combat deep fake. But NFTs, on the other hand, are still far away from being the standard on blockchains like Ethereum.
