Water waste

In the UAE’s arid climate, small shrubs, bushes and flower beds usually require about six litres of water per square metre, daily. That increases to 12 litres per square metre a day for small trees, and 300 litres for palm trees.

Horticulturists suggest the best time for watering is before 8am or after 6pm, when water won't be dried up by the sun.

A global report published by the Water Resources Institute in August, ranked the UAE 10th out of 164 nations where water supplies are most stretched.

The Emirates is the world’s third largest per capita water consumer after the US and Canada.

Know your cyber adversaries

Cryptojacking: Compromises a device or network to mine cryptocurrencies without an organisation's knowledge.

Distributed denial-of-service: Floods systems, servers or networks with information, effectively blocking them.

Man-in-the-middle attack: Intercepts two-way communication to obtain information, spy on participants or alter the outcome.

Malware: Installs itself in a network when a user clicks on a compromised link or email attachment.

Phishing: Aims to secure personal information, such as passwords and credit card numbers.

Ransomware: Encrypts user data, denying access and demands a payment to decrypt it.

Spyware: Collects information without the user's knowledge, which is then passed on to bad actors.

Trojans: Create a backdoor into systems, which becomes a point of entry for an attack.

Viruses: Infect applications in a system and replicate themselves as they go, just like their biological counterparts.

Worms: Send copies of themselves to other users or contacts. They don't attack the system, but they overload it.
