Answer:

Nearly 80 per cent of organisations in North America and Europe were victims of cyber attacks last year and nearly half of cyber attacks used malware hidden in encrypted traffic to evade detection, a report said on Wednesday.

The encryption technology that is crucial to protecting sensitive data in transit such as web transactions, emails and mobile apps, can allow malware hiding inside that encrypted traffic to pass uninspected through an organisation’s security framework.

The report by US-based security company A10 Networks in partnership with Ponemon Institute surveyed 1,023 IT and IT security practitioners in North America and Europe, highlighting the challenges these professionals face in preventing and detecting cyber attacks.

Sphinxa [80]

Answer:

P_4_{(I)}+5O_2_{(g)}+6H_2O_{(l)}\rightarrow +4H_3PO_4_{(l)}

Explanation:

The first step is:

P_4_{(I)}+5O_2_{(g)}\rightarrow 2P_2O_5_{(g)}

Second step is:

P_2O_5_{(g)}+3H_2O_{(l)}\rightarrow 2H_3PO_4_{(l)}

Multiplying second step by 2, and adding both the steps, we get that:

P_4_{(I)}+5O_2_{(g)}+2P_2O_5_{(g)}+6H_2O_{(l)}\rightarrow 2P_2O_5_{(g)}+4H_3PO_4_{(l)}

Cancelling common species, we get that:

P_4_{(l)}+5O_2_{(g)}+6H_2O_{(l)}\rightarrow +4H_3PO_4_{(l)}
