What a Disgruntled Ex-Employee Who Cost a Company $678,000 Can Teach All Business Owners

What a Disgruntled Ex-Employee Who Cost a Company $678,000 Can Teach All Business Owners

In early June, Kandula Nagaraju, a 39-year-old former National Computer Systems employee from India, received a two-year, eight-month prison sentence for unauthorized access and deletion of 180 test servers at his previous workplace.

Despite being terminated in October 2022 due to performance issues, Nagaraju retained access to company systems. He used this access to develop and execute scripts that deleted the servers. This action cost NCS approximately $678,000 to rectify. Fortunately, his nefarious deeds did not compromise sensitive data as the servers were isolated and used for app testing. But, the company still suffered an enormous financial loss. Plus, things could have been a lot worse.

This single case serves as a critical reminder: ex-employees can still be a liability, and if they maintain their insider access, they can exploit said access to inflict extensive damage. Not only monetarily, but on a much wider and more consequential scale. So harmful, that it could bring a company down and ruin its reputation to the point of no return.

Why Businesses Should Always Delete the Credentials of Former Team Members

Sadly, Nagaraju is just one example of many. Several companies have suffered immensely – but unnecessarily – simply because those organizations did not take the proper steps to protect themselves. Instead, they were complacent or too late to act and the results were disastrous. Because of these instances, businesses should always remove ex-employee credentials to keep their corporate data and work product secure for several reasons:
  • Data security. Ex-employees may still have access to sensitive company information, such as customer data, trade secrets, or financial information. Removing their access ensures that this data remains secure and is not accessed or misused by unauthorized individuals.
  • Prevent unauthorized access. Even if an ex-employee has left the company – even on good terms – there is always a risk that they could use their access to the company’s systems to make changes or access data without approval. Removing their credentials prevents this from happening.
  • Compliance. Many industries have regulations that require companies to protect sensitive data. By removing ex-employee credentials, companies can ensure they are meeting these compliance requirements.
  • Insider threats. Ex-employees may be disgruntled or may have left the company under less-than-ideal circumstances. They could potentially use their access to company systems to sabotage the company or steal data. Removing their credentials helps to mitigate this risk.
  • Avoid confusion. If an ex-employee’s credentials are not removed, it can lead to confusion about who has access to what. This can make it more difficult to manage access to systems and data.
And last but not least, data breach prevention. If an ex-employee’s credentials are compromised, it could lead to a data breach. Removing their credentials helps to prevent this. By deleting their access, companies have less risk of sensitive information getting out into the public domain. Because once that data is out, it’s up for grabs for anyone to capture it.

So, businesses of all sizes should have a process in place to address such security issues. When an employee leaves the company voluntarily or a team member is terminated, that person’s credentialed access should immediately be removed. Additionally, steps must be taken to fill that new void to ensure workflow continues virtually uninterrupted in order to meet benchmarks and deadlines. Moreover, to keep proprietary data safe.

New to Hiring, Here’s How to Spot Resume Red Flags

April 8, 2021 No Comments

It’s often said the first hire is the hardest, and that’s inescapably true for several reasons. Foremost, it’s because when you hire an employee, you’re hiring someone to represent your business. Which is to say, you’re entrusting them with your company’s entire reputation. Then, there’s the matter of consistency, even if that person has the competence. In other words, being able to do the job well over and over again. But, that’s not all, your first hire must be cost effective, helping your business to earn more than it did before. So, it’s no wonder business owners procrastinate as long as they can, putting off their first hire. What Resumes Are (and Aren’t) Of course, there’s the conundrum of where to begin and finding a good fit. This is where the resume comes into play, although you may not be very familiar with qualifying a person’s capabilities from a sheet or couple of sheets of paper. On average, hiring professionals spend just 7 seconds looking over each resume. That’s not a lot of time, and especially seems short if you’re doing it for the first time. Do you know who you are hiring? You need to review each resume, cover letter and job application that you receive with care. You want to ensure that the candidates you consider hiring are who they say they are and that their credentials are valid and match your needs. —The Balance Careers The good news is, you can get a lot out of just about any resume, if you know what to look for. Obviously, you have to start with an understanding of what a resume is and what it isn’t. A resume is simply a summary of a person’s qualifications and their competencies, along with their work history. That’s about it, what a resume isn’t, is a tell-all that will reveal all a person’s strengths and weaknesses. How to Spot Resume Red Flags The simple fact of the matter is that a resume only provides the information the applicant furnishes. Meaning, it will only tell you what the applicant wants you to know. However, this doesn’t mean it can’t give you some very key clues that you can use to your advantage. Here are the biggest red flags resumes can reveal: Inexplicable or unexplained gaps. A resume with big gaps, particularly between positions, is one that tells you a whole lot. Someone who has large gaps between jobs is likely an applicant you’d probably be better off without. Rock star qualifications. Conversely, if an applicant’s resume is packed with too much good news, it’s probably too good to be true. A resume with a cornucopia of qualifications is likely full of exaggerations, embellishments, half-truths, and more misleading information. tOO mAny TyPoes. Poor spelling, bad grammar, sloppy punctuation spell b-a-d n-e-w-s. If someone doesn’t pay close attention to the way they present his or her self on paper, he or she isn’t really interested impressing potential employers. Of course, these aren’t the only red flags you might find on a resume. Applicants who send their resumes from current employers’ email systems are telegraphing they’re not respectful of others’ time and resources. Unusual employment histories are also a red flag. People who hop from one industry to another do so for reasons that should concern you. What other red flags do you look for on resumes? Please take a quick moment to share your experiences and thoughts. After all, your perspective just might help someone else out! Interested in learning more about business?

How to Set Performance Baselines for Quarterly Employee Evaluations for the Year Ahead

January 3, 2024 No Comments

How to Set Performance Baselines for Quarterly Employee Evaluations for the Year Ahead We all know the drill: the calendar year flips, dreams are dreamt, and then you’re face-to-face with the annual performance review behemoth. And while quarterly check-ins might feel like another item on the ever-growing to-do list, they’re actually your secret weapon for keeping everyone – you and your team – motivated, on track, and slaying those business goals. But the key to making these quarterly chats sing? Setting clear, impactful baselines that guide the way. Setting Realistic Expectations but With Confidence Let’s ditch the dry performance review templates and talk real – real goals, real progress, and real conversations that ignite your team’s potential. Buckle up, friends, because we’re diving deep into the world of crafting practical and persuasive baselines for your quarterly employee evaluations, all with a healthy dose of small business swagger. Now, let’s get into the nitty gritty and go step-by-step on how to set performance baselines for quarterly employee evaluations: Step 1: Big Picture Vision, Microscopic Focus Before we zoom in on individual roles, let’s paint the bigger picture. Where do you see your business soaring this year? Define your key company goals, the ones that make your entrepreneurial heart skip a beat. Think of increased revenue, expanded product lines, or dominating that local market share. Get specific, dream big, and write these down – they’ll be your North Star throughout the year. Step 2: Deconstructing Dreams into Doable Deeds Now, let’s break down those dreamy company goals into bite-sized chunks for each quarter. Think of them as the stepping stones on your path to success. What measurable milestones need to be reached each quarter for your vision to unfold? And, as always, be SMART about it – Specific, Measurable, Achievable, Relevant, and Time-bound. Don’t overwhelm your team with a Mount Everest of tasks; focus on the key metrics that drive progress. Step 3: Mapping Personal Paths to Collective Triumph Here’s where the magic happens! Align individual roles with those quarterly company goals. What specific contributions can each team member make to hit those milestones? Tailor these individual baselines to each role’s strengths and responsibilities. Think sales targets for your star hustler, conversion rate improvements for your marketing whiz, and customer satisfaction benchmarks for your service champion. Remember, these baselines should be challenging yet achievable, sparking that “I got this!” feeling in your team. Step 4: Metrics that Matter (and Don’t) Numbers talk, but not all those figures sing. Choose metrics that truly reflect individual and collective progress toward your goals. Sales figures are great, but what about customer retention rates or lead generation efforts? Don’t get bogged down in vanity metrics that look good on paper but don’t tell the whole story. Focus on the data that drives actual impact and motivates your team to go the extra mile. Step 5: Communication is King (or Queen, or Both!) Open and honest communication is the engine that fuels high-performing teams. Share your company goals and individual baselines with your team in a clear, transparent way. Get them involved in the process, gather their feedback, and make sure everyone feels like they’re rowing in the same direction. Remember, these baselines aren’t meant to be shackles, but stepping stones – a roadmap for collaborative success. Step 6: Check-Ins, Tweaks, and Cheers! Quarterly reviews aren’t just about checking boxes; they’re opportunities for growth, celebration, and course correction. Use these check-ins to gauge progress, adjust baselines if needed, and offer actionable feedback that empowers your team to reach their full potential. And don’t forget the high fives and virtual confetti showers! Recognizing achievements motivates continued excellence and keeps the fire burning bright. How It All Wraps Up Setting quarterly baselines takes effort, yes, but the rewards are immense. You’ll see increased employee engagement, boosted morale, and a laser-sharp focus on achieving your shared vision. So, ditch the performance review dread and embrace these baselines as the springboard to your small business success story. Remember, you’ve got this – and your awesome team by your side!
