London Businesses & The Threat of Cyber Attacks

As technology continues to grow, the demand for businesses in London to constantly update their cyber-security practices and policies is more crucial than ever. From a small company to medium-sized business and large organizations, no one is safe when it comes to cyber-attack. Security measures that worked some years back might be obsolete today.

Cyber-security is a big topic in London. This is because more than 20 percent of small and middle-sized companies have fallen victims of cyber-attacks. Even though clear evidence shows that majority of cyber-attacks result from poor password management and employee lack of knowledge, most companies are doing little to boost cyber-security. Actually, a good number of organizations do not know the best strategies to use to counter the attacks.

But it is important to note that there is no single policy or practice that can address cyber threats. This is because there are a number of cyber threats for a strategy to offer complete protection. Hence, it is essential for every company to have a comprehensive cyber-security strategy and to engage the best IT service companies to safeguard the most sensitive data of the corporation.

So, what are the biggest cyber threats to business in London and how can they protect themselves?

Biggest Cyber-security threats to businesses in London

  1. Phishing attacks

More than 70 per cent of business in London report of being victims of phishing or attempted phishing attacks. Phishing is a social attack that is designed to steal personal information such as credit card credentials, user log-ins or business information. It comes from a supposed legit source such as personal contact, banking institutions, or well-known websites. By replying to such emails or clicking the links to provide the required information, the information is sent to the attacker.

The best way to limit phishing attacks is raising awareness among the employees. Have training and educate all the employees about the menace and the risks.

  1. Ransomware

Ransomware is a big cyber threat in London. It is an attack that focuses on getting an encryption-malware onto your company’s network. In most cases, it comes through email links and attachments. And once the malware in your network, it starts to encrypt all the files to make them inaccessible. Later a message is generating telling you to pay some money to get you’re an encryption key. To limit ransomware risk, you need to:

  • Educate all your staff
  • Use updated malware scanning programs
  • Have a remote data backup
  1. DDoS Attacks (Distributed-Denial of Service)

DDoS has remained a major cyber threat to many companies in London. It is an attack where a number of sources target a specific website, web-server, or a known network device. This leads to crashing or slowing down the website or server making it unavailable to the users. The attacks can even confuse your company security team.

The best strategy to prevent a DDoS attack is having sufficient capacity that can handle a fake-bandwidth and having a program that can blacklist IP addresses that are not identified.

  1. Hacking

Hacking is another big cyber threat to small and middle-sized organizations. It is an attack by people outside your business to your server. Whether it is one computer that lacks security measure or it’s all the devices, the attackers just need an entry point to enter into your network.

Therefore, if you have a new security strategy for your company’s network, make sure the solution is applied to all computers and laptops. Otherwise, that one computer that is not well-protected could become a route for an attack.

  1. Advanced-Persistent Threats (APT)

This is an attack where a code is allowed to enter into your company’s network and steal information without avoiding detection. The code can remain into your company’s network for a long time stealing information such as log-in details, financial information, or security information. APT gains access via an email, program, file or network.

Even though it might be hard to detect an APT, there are several measures your company can have to prevent the attack. Use of firewalls and anti-virus and educating employees can slightly help. But safeguarding your financial data, having end-to-end protection across your business, and hiring IT service companies is the best way to prevent an attack.
