Consider the universal relation r= {a, b, c, d, e, f, g, h, i, j} and the set of functional dependencies f.
f = {{a, b} _{c, d},
{d}=> {e, f, g},
{f, g}_{h},
{a}+{i},
{a, b} {e, g},
{a, i} + {i, j}}
(a) what is the closure of the set {a, d}?
(b) what is the key for r?
(c) what is the minimum cover for the set of functional dependencies f?
(d) decompose r into 2nf.
(e) decompose r into 3nf.

You are working as a security analyst in a company xyz that owns the whole subnet range of 23.0.0.0/8 and 192.168.0.0/8. while monitoring the data, you find a high number of outbound connections. you see that ip's owned by xyz (internal) and private ip's are communicating to a single public ip. therefore, the internal ip's are sending data to the public ip. after further analysis, you find out that this public ip is a blacklisted ip, and the internal communicating devices are compromised. what kind of attack does the above scenario depict?
