Telecommunications providers have an incredibly important role when it comes to systems security.
Not only do they hold large amounts of data on their customers, but their networks also carry sensitive information, such as financial transactions, personal data and confidential business information. Telecommunications networks are critical infrastructure, therefore any breach in system security can have severe consequences, including financial losses, reputational damage and legal liabilities.

Telecommunications networks face various security threats, such as hacking, malware, phishing and denial-of-service attacks. These threats can be initiated by both external and internal sources such as state-sponsored hackers or by employees intentionally or unintentionally compromising the network’s security.

To mitigate these risks, telecommunications networks must implement robust security measures to protect their systems and data. Providers also must comply with regulatory requirements to ensure the protection of personal information. The Telecommunications Security Act, which became law in 2021, gives the UK government powers to boost the security standards of the country’s mobile and broadband networks.

The PTT online course “Telecommunications systems security” provides an overview of the protection of personal data held by telecommunications providers against misuse and the protection of telecoms systems against intrusion and fraudulent misuse.
