Know the biggest Hardware Security Threats caused by Cyber Attack
Table of Contents
The upward thrust of the world’s massive net in the Nineties spread new possibilities and fostered new establishments; however, it added unique connection drawbacks with it. Spam began to flood email accounts, and computer viruses wreaked havoc on corporate networks. Computer hacking is a new danger that includes entering your computer, collecting personal information, misleading you into exposing private data, and utilizing that data to steal and extort personal information such as corporate secrets, bank account credentials, and even people's identities.
What is the definition of a computer hacker?
Computer hackers break into internet-connected devices such as computers, tablets, and smartphones to steal, alter, or delete data.
Hackers, like other criminals, frequently break into equipment with ill intent. (White hat hackers, who firms employ to get into their gear to identify security weaknesses that need to be patched, are an exception.) Hackers may try to steal, change, or erase information on your devices, and they frequently do so by installing malware (malicious software) that you are unaware of. These criminals may gain access to your most sensitive information.
Some of the reasons why computer hackers break into equipment are as follows:
Financial crimes are a type of fraud. We've all heard the story of someone looking through their credit card account and seeing transactions they didn't make. These bogus transactions are frequently the consequence of computer hackers acquiring credit card numbers, checking account information, or other financial information.
Vandalism. Because hacking has its subculture, some hackers may feel compelled to vandalize certain websites to impress their peers. Doesn't it seem absurd? Don't make the mistake of dismissing this reason; according to Malwarebytes, it's very prevalent.
Hacktivism. This portmanteau refers to a type of hacking that is similar to vandalism. For political purposes, some hackers may wish to change or destroy particular websites.
Company espionage is a term used to describe the act of stealing records from spying that happened long before internet technology, and hacking has just accelerated the accessibility of espionage to the familiar individual.
How to Protect Your Computer Against Hackers
Despite the prevalence of computer hackers, most companies use the internet to check their finances, purchase and keep inventory, execute marketing and public relations campaigns, communicate with consumers, use social media, and do other vital tasks. Even at large organizations with extensive security procedures in place, we continue to hear about catastrophic computer intrusions.
Can the hardware of a computer suffer a cyber attack?
IoT gadgets are hazardous since they are self-contained. It's more challenging to pinpoint the exact time an attack happened on an IoT component than it is to do so for servers, desktops/laptops, or smart gadgets. That isn't to say that these gadgets aren't vulnerable to hardware security concerns. The following are examples of common hardware security flaws:
Hardware flaws in the real world
- Passwords that are set by default. This is primarily a problem with low-cost IoT devices and hardware that utilize default passwords out of the box. These passwords are then often introduced to company networks, with little consideration given to the risk involved.
- Local access that isn't password-protected. A controlled Ethernet or serial interface may be used to access IoT, IIoT, and intelligent building devices in various circumstances. A bad actor may attack a company's infrastructure by tampering with these devices while visiting the office, warehouse, or manufacturing facility if these connections aren't closed down — both in terms of configuration and physical security.
- Device firmware/BIOS/UEFI (Unified Extensible Firmware Interface) is out of date. Innovative HVAC systems, industrial plant robots, and other IP-connected IoT/IIoT components aren't always IT security experts. Firmware is frequently infected with bugs and security vulnerabilities. Sloppy patch management exacerbates this risk, as many IT departments fail to upgrade the firmware on these devices when security fixes are published.
- There is no encryption. In operational technology equipment increasingly becoming IP-connected, encryption, whether at rest or in motion, is frequently inadequate. Unencrypted data can be obtained either across the network or directly from stolen devices that have unencrypted data stored in them.
Details concerning hardware security risks and vulnerabilities are frequently reported in the press. Security experts warned in early 2020 about a security hole uncovered in some Intel CPUs that let hackers install malware at the hardware level, leaving OS-based malware defense useless.
Security approach for hardware
Software-centric security problems are not the same as hardware security flaws. For one thing, hardware problems are more likely to impact specialized items that IT security experts are unfamiliar with. To assist safeguard your company, take a network inventory to identify all of the linked hardware devices. Next, ensure the manufacturer has sufficient documentation and a procedure for obtaining and upgrading security and firmware fixes. Ideally, these patches should be applied automatically.
That is also a terrific possibility to think again about the devices that connect to your community and decide whether or not or no longer you believe them. In rare situations, you may find out that the hardware has reached the quit of its beneficial lifestyle or is now not supported. In a few instances, the hardware may additionally come from a dubious source. Anyways, the company should determine how dangerous it is ready to accept antique gear simply. If it's far extra smart to purchase more modern technology, this is more likely to be included and patched regularly.
