CFDs are complex financial instruments and carry a high level of risk due to leverage. A significant proportion of retail investors incur losses when trading leveraged products such as CFDs. You should carefully consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your capital.
If you’re wondering what availability is in the context of IT security, it’s the ability to ensure that data and systems are accessible when authorized users need them. Along with confidentiality and integrity, it forms one of the three pillars of information security. In the financial world, availability determines whether you can access your trading platform, your online banking, or your funds at the exact moment you need them.
The availability of information is not an abstract concept for those who trade in the markets. If your broker’s platform goes down during a volatile trading session, you can’t close positions or execute orders. If your online banking becomes inaccessible, you can’t make transfers or check balances.
Minutes of downtime can translate into real losses. That’s why financial platforms invest in redundant infrastructure and business continuity plans to minimize disruptions.
Organizations implement multiple layers of protection to keep their systems operational. No single measure guarantees continuous access; combining several reduces the risk.
Duplicate servers, alternative data lines, and backup power sources ensure that if one component fails, another automatically takes its place. The user is unaware of the interruption.
Regular backups of data and configurations allow the service to be restored after an incident. The speed of that recovery determines how long the system remains offline.
The causes of availability loss in information security are, for the most part, identifiable and preventable.
DDoS attacks. These saturate the server with fake traffic until it becomes inaccessible.
Ransomware. This encrypts data and blocks access until a ransom is paid.
Hardware failures. A disk, a server, or a data line can fail without warning.
Human error. Incorrect configurations or poorly executed updates can bring systems down.
The 2017 WannaCry attack affected thousands of organizations in multiple countries. Companies with up-to-date backups restored operations within hours. Those without backups lost data and weeks of productivity.
A cryptocurrency exchange becomes inaccessible for 45 minutes due to a DDoS attack. During that time, Bitcoin drops by 8%. Traders with open positions cannot execute stop-loss orders or manually close positions. When service is restored, many find themselves facing losses that could have been avoided with access to the platform.
When a platform fails, the negative reaction can make the situation worse.
Entering credentials on alternative sites without verifying their authenticity.
Not having stop-loss orders set up in advance.
Relying on a single device or access method.
Although availability depends on the platform, you can reduce your exposure.
Set stop-loss orders on all open positions as a standard practice.
Have access via a mobile app as an alternative method.
Choose platforms with a solid track record of uptime.
Availability ensures that data and systems are accessible when you need them. In finance, it’s the difference between managing your positions and being locked out at the worst possible moment. Choosing platforms with redundant infrastructure and maintaining your own safeguards reduces that risk.
