BITBOX is a trusted platform where users can exchange cryptocurrencies.
It is necessary to make this platform secure since attackers have been targeting cryptocurrency exchanges to steal funds residing in user wallets. Many cryptocurrency exchanges have already been attacked in the past.
We have studied cryptocurrency exchange hacks in order to make BITBOX user assets safe against cyber attacks using two security strategies: one is layered security and the other one is defense in depth.
Layered security is the combination of a series of security counter-measures, each layer protects against a different attack vector. This way, each counter-measure can cover gaps of the others.
Defense in depth, on the other hand, assumes a broader range of scenarios which can not all be covered using technological means or new security threats that are not traditionally recognized such as disaster recovery, malicious insider threat, sophisticated(or zero-day) attack, etc.
In this talk, he will share LINE’s security strategies and a cryptocurrency exchange security architecture focused on protecting user assets even when the adversary gain full control of the system.
