The internet has transformed business, allowing even small enterprises to trade on a global scale; however, it has also brought challenges. Of these, the greatest is the threat of a cyberattack, which can be devastating for businesses of any size.
Common threats
There are a number of threats commonly used by cybercriminals. These include phishing attacks, which target users through social media messaging or email by posing as a trusted sender to trick the user into giving information.
Ransomware is a commonly used form of malware that allows criminals to hold their victim’s data hostage, often threatening to publish it unless a ransom is paid. Another form of malware is spyware, which gathers data such as bank accounts and login credentials that can either be sold or used to commit identity fraud.
Viruses and worms are malicious programs that exploit software vulnerabilities. They can be used to gain unauthorised access or corrupt files.
Prevention
Prevention is better than cure, so use good security software and carry out regular website security checks. If you do not have in-house cybersecurity experts, you can use a professional service such as www.etempa.co.uk/website-security-checks/.
The consequences
A successful cyberattack can be financially devastating. In addition to the possibility the business has been stolen from, the attack can have other financial implications. The business may have to pay a ransom and will also incur expenses in fixing the damage; what’s more, there may be fines for lax security. Perhaps worst of all is the damage to the reputation of the business, as customers will no longer trust the business with their information. This can result in a massive drop in business.
The impact of malware on systems can result in disrupted business operations. It may even be necessary for a business to be taken offline for a while, resulting in a further loss of income. Businesses may also lose their intellectual property, such as product designs, new technologies, and corporate strategies. This can considerably set a business back, as it loses work in which it has invested time and money.
How malware spreads through a company network
Malware, short for malicious software, is an umbrella term for hostile programs including trojans, ransomware, spyware and adware. It arrives as executable code, scripts, active content or software, and is often activated by a member of staff who does not realise what they have opened. Because it can be hard to spot, it may spread across a computer and then the wider network before anyone notices.
Once active, malware can corrupt system files, slow machines down, display unwanted adverts and gather private information. Some types are designed to stay hidden, spying on users or stealing data over long periods. Spyware can even be bundled with legitimate software, quietly tracking activity and sending data back to remote servers.
Protection starts with reliable antivirus software that detects malware and stops it causing harm. Staff awareness matters as well, since so many infections begin with a user action. For larger networks, an experienced network security firm can design a threat management system that suits the business and keeps watch for intrusions.
