COMMENT network from known cybercriminal scans. It instantly recognises and blocks traffic in real time from known attack sources to protect networks from new and future threats. Thunder TPS’s on-premise protection also integrates with Verisign’s cloud-based DDoS Protection Services to deliver cloud- bursting capabilities that offload attack mitigation to the cloud. The Verisign service is backed by global points of presence and multiple terabits per second of global capacity. It ensures your network won’t collapse under the weight of a high-volume attack. And for an additional layer of defence, A10’s DDoS Security Incident Response Team (DSIRT) puts a team of DDoS fighting experts at your fingertips 24/7 to provide assistance in mitigating attacks in real time, as they’re happening. A strong DDoS defence solution, like A10 Thunder TPS, can help protect against threats now and threats that could spring up in the future. So if Reaper starts launching DDoS attacks, or researchers uncover the next big botnet, you’re covered, and you won’t have to fear the Reaper. n Could the blockchain enforce PoPI in South Africa? Blockchain’s traceability feature may go hand in hand with PoPI enforcement, explains Vishal Barapatre, CTO at In2IT Technologies. T he Protection of Personal Information (PoPI) Act is looming on our horizon. South African organisations are busily preparing for it despite there still being much debate about what the real impact will be and whether or not it will be truly effective. However, one thing is certain, a legislation that protects personal information is necessary, and any technology which could support PoPI within the business should be seriously considered. One technology that seems purpose- built for protecting information is the blockchain. Although one of the selling points of blockchain technology is its inherent transparency, it certainly has effective security measures. The blockchain and PoPI compliancy With the implementation of PoPI, organisations will need to be more sensitive around the privacy of their customers’ information. To do so, they will have to be more organised around the storage, use and dissemination of this data so as not to overstep the bounds of PoPI, and to take care of their customers’ privacy. There needs to be a level of ‘proof’ of where the data is kept, how it is used and who has access to it at any given time. 24 INTELLIGENTCIO The blockchain is a shared digital transactional ledger that securely records and regularly reconciles transactions of virtually anything of value. Therefore, blockchain provides accurate traceability and in turn, promotes accountability. There is also the security factor, which appeals to compliancy requirements of PoPI. The blockchain offers unparalleled security features, given its multi- verification nature and tamper-proof mechanism of protecting already verified data. If current trends are anything to go by, the blockchain will only get more secure. Any concerns? The question around transparency still exists. Surely a platform that specifically highlights transparency as a benefit automatically precludes it from being suitable for an act which stresses the protection of a person’s privacy? Not necessarily . . . A blockchain can be programmed with certain predefined rules, or permissible actions, around what may be done with any piece of personal information, based on the type of information it is. Although the information may be visible to anyone with access to Vishal Barapatre, Chief Technical Officer, In2IT Technologies the blockchain on which it sits, these parameters automatically create alerts when certain data is accessed, used, or disseminated in any way that falls outside their bounds. Granted, there is still the risk that the data may be accessed by unauthorised individuals, but the organisation will be alerted and can take immediate action. The blockchain provides verifiable proof of who accessed the data illegally, for what reason, and what was done with the data. It can then be raised with the PoPI regulator, if required, or can take internal action, as desired (or as required by policy and/or law). The only real grey area with using the blockchain for complying with data storage, is that there will exist a permanent, unerasable record of the data, indefinitely. PoPI does define that an organisation must honour an individual’s request for their data to be removed once it is no longer in use. The immutability of the blockchain could prove a problem, nevertheless an organisation still retains control of who may or may not access the data, and could exercise that control to ensure that the data remains all but invisible for its lifespan. n www.intelligentcio.com
