Q1: My Company Wants To Store Credit Card Data What Methods Can We Use
A: Most merchants that need to store credit card data are doing it for recurring billing. The best way to store credit card data for recurring billing is by utilizing a third party credit card vault and tokenization provider. By utilizing a vault, the card data is removed from your possession and you are given back a token that can be used for the purpose of recurring billing. By using a third party, you move the risk of storing card data to someone who specializes in doing that and has all of the security controls in place to keep the card data safe.
If you need to store the card data yourself, your bar for self-assessment is very high and you may need to have a QSA come onsite and perform an audit to ensure that you have all of the controls in place necessary to meet the PCI DSS specifications.

The key question to ask is definition of “IMPORTANT”. Is it important to the managers , important to the end consumer or important for Amazon. The first one needs to be thrown out immediately and the others must be quantified based on achievability, impact on end user and ROI.Less
I would say whichever is more valuable to customer & amp gives competitive advantage to Amazon.Less
In addition to the above suggestions, I would look at cost and time to market and then score both options. Then define value metrics. The cheapest and most valuable either as a technology sustainer or for customer wins. Given that it’s Amazon, customer value will hold up the highest as one of their corporate culture virtues.Less
Try to define “scale”, ask for clarifications. Are we trying to scale to more users or to more ad providers? Are there any current bottlenecks? What is the goal here? How about we improve the experience by providing more relevant ads? etc…Less
Its such a tricky question. I guess its by the analytic we use to know the page views and all..Less
I’d ask ‘why’?Something radically changed since the last time this was discussed. Understanding what it was that changed is critical to determining the best course of action.

Encryption is a crucial component of security architecture and is necessary to safeguard data from unauthorized access.
How Frequently Should Businesses Conduct Security Audits
A security architect’s duties also include conducting security audits. Based on their size and the complexity of their security systems, firms should conduct security audits at least once a year, if not twice or even three times. Regular audits enable Cyber Security Architects to see any faults before they cause my clients serious trouble. Additionally, they can use the findings of each audit to develop a strategy for enhancing the company’s overall security system.

What Differentiates A Vpn From A Firewall
A VPN establishes a secure connection across an existing network, whereas a firewall defends a network from outside threats.
A firewall is excellent for securing a single device or site, but it is less effective in tying together numerous places.
Because a VPN uses encryption to provide a secure tunnel between two points, it is more suited for tying together remote users. However, this implies that anyone who has access to the tunnel can view the data being sent.

Q: What Are The Pci Compliance Levels And How Are They Determined
A: All merchants will fall into one of the four merchant levels based on Visa transaction volume over a 12-month period. Transaction volume is based on the aggregate number of Visa transactions from a merchant Doing Business As . In cases where a merchant corporation has more than one DBA, Visa acquirers must consider the aggregate volume of transactions stored, processed or transmitted by the corporate entity to determine the validation level. If data is not aggregated, such that the corporate entity does not store, process or transmit cardholder data on behalf of multiple DBAs, acquirers will continue to consider the DBAs individual transaction volume to determine the validation level.
Merchant levels as defined by Visa:
|Any merchant processing 20,000 to 1M Visa e-commerce transactions per year.|
|4||Any merchant processing fewer than 20,000 Visa e-commerce transactions per year, and all other merchants regardless of acceptance channel processing up to 1M Visa transactions per year.|
* Any merchant that has suffered a breach that resulted in an account data compromise may be escalated to a higher validation level.

Once a company has reduced the scope of the problem as much as possible, via point-to-point encryption, tokenization and outsourcing, the next step is to ensure that all the proper controls are in place on the data that’s left in the system. Companies need to be careful to avoid a checklist-style approach to compliance. “Unfortunately, we have seen that concentrating strictly on standalone compliance efforts can produce a false sense of security and an inappropriate allocation of resources,” says PricewaterhouseCoopers’ Ames.
Instead, PricewaterhouseCoopers recommends a more comprehensive, risk-based approach. “Use the PCI DSS as a baseline controls framework that is supplemented with risk management practices,” Ames says. “This gives the team an understanding of where they need to focus effort in alignment with the threat landscape.”
Then, companies need to make sure that they have processes in place to ensure that they stay compliant. That means that they need a way to monitor the controls, and if one fails, there’s a process to identify and correct the problem quickly.
